(sorry for possible cross-posting) We have the pleasure to announce the following two seminars, in University of Padova, Italy Department of Mathematics, via Trieste 63 room 1BC/45, 1st floor Friday, April 24 9.00 Zorana GRBAC: "Discrete-tenor interest rate models based on polynomial preserving processes" ABSTRACT: Based on the class of polynomial preserving Markov processes, we construct families of positive martingales, which are monotone with respect to some parameter. Such martingales are particularly suitable for modeling of discretely compounded forward interest rates via additive constructions. This includes Libor-type models, as well as extensions to the multiple-curve term structure. The main advantage of this model class is the possibility to obtain semi-analytic pricing formulas for both caplets and swaptions that do not require any approximations. Moreover, additive constructions allow to easily ensure, if desired, properties such as positivity of interest rates and spreads and monotonicity of spreads with respect to the tenor - in view of the current market situation a model in which the reference OIS interest rates can become negative and the spreads still remain positive is of particular interest. Examples of tractable and flexible model specifications that we study include quadratic OU-Gaussian and OU-L?vy processes, as well as linear models. We discuss the efficient option pricing via Fourier methods and develop the necessary exponential transform formulas for polynomial preserving processes. This is joint work with K. Glau and M. Keller-Ressel. 10.00 Antonis PAPAPANTOLEON: "An equilibrium model for spot and forward prices of commodities" ABSTRACT The aim of this project is to determine the forward price of a consumption commodity via the interaction of agents in the spot and forward commodity market. We consider a market model that consists of three agents: producers of the commodity, consumers and financial investors (sometimes also called speculators). Producers produce a fixed amount of the commodity at each time point, but can choose how much they offer in the spot market and store the rest for selling at the next time period. They also have a position in forward contracts in order to hedge the commodity price uncertainty. Consumers are setting the spot price of the commodity at each time point by their demand. Finally, investors are investing in the financial markets and, in order to diversify their portfolios, also in the forward commodity market. The equilibrium prices for the commodity are the ones that clear out the spot and forward markets. We assume that producers and investors are utility maximizers and have exponential preferences, while the consumers' demand function is linear. Moreover, the exogenously priced financial market and the demand function are driven by L?vy processes. We solve the maximization problem for each agent and prove the existence of an equilibrium. This setting allows to derive explicit solutions for the equilibrium prices and to analyze the dependence of prices on the model parameters and the agent's risk aversion. This is joint work with Michail Anthropelos and Michael Kupper. After the two seminars, the defenses of a PhD thesis will take place: 11.00 Giulio MIGLIETTA: "Topics in interest rate modeling" (supervisor: Martino Grasselli) See you all in Padova!

seminario Valeria Bignozzi in Bicocca
by Fabio Bellini 20 Apr '15

20 Apr '15

Il giorno venerdì 24 aprile alle ore 14.00 presso la aula seminari del Dipartimento di Statistica e Metodi Quantitativi della Università di Milano-Bicocca (edificio U7, IV piano), la dott.ssa Valeria Bignozzi della Università di Firenze terrà un seminario su: Reducing model risk using positive and negative dependence assumptions Abstract We give analytical bounds on the Value-at-Risk and on convex risk measures for a portfolio of random variables with fixed marginal distributions under an additional positive dependence structure. We show that assuming positive dependence information in our model leads to reduced dependence uncertainty spreads compared to the case where only marginals information is known. In more detail, we show that in our model the assumption of a positive dependence structure improves the best-possible lower estimate of a risk measure, while leaving unchanged its worst-possible upper risk bounds. In a similar way, we derive for convex risk measures that the assumption of a negative dependence structure leads to improved upper bounds for the risk while it does not help to increase the lower risk bounds in an essential way. As a result we find that additional assumptions on the dependence structure may result in essentially improved risk bounds (joint work with G. Puccetti and L. Ruschendorf). Tutti gli interessati sono invitati a partecipare.

Seminari di Klaus Schredelseker e Eckhard Platen a Firenze
by Giacomo Scandolo 17 Apr '15

17 Apr '15

Nell'ambito del Corso di Laurea Magistrale in Finance and Risk Management (FiRM) dell'Università di Firenze i Proff Klaus SCHREDELSEKER (University of Innsbruck) e Eckhard PLATEN (University of Technology, Sydney) terranno i seguenti seminari presso il Dipartimento di Scienze per l'Economia e l'Impresa Edificio D6, via delle Pandette, 32, Firenze Tutti gli interessati sono invitati a partecipare Gli abstract degli interventi sono riportati in basso. ============================================================= Prof Klaus SCHREDELSEKER Martedì 5 Maggio, 14.00-16.00, aula D6/007 ''Financial Analysis and Efficient Markets '' Mercoledì 6 Maggio, 12.00-13.30 e 14.30-16.00, aula D6/102 "Information Economics applied to Financial Markets " ============================================================= Prof Eckhard PLATEN Giovedì 7 Maggio, 10.00-12.00, aula D6/105 ''Numerical Solutions of Stochastic Differential Equations with Jumps in Finance '' Venerdì 8 Maggio, 10.00-12.00, aula D6/013 "A Benchmark Approach to Finance " ============================================================= Abstract. ''Financial Analysis and Efficient Markets '' (Schredelseker) Financial Analysis is the basic of any type of financial reasoning (portfolio theory, capital market theory, derivatives). How it has to be done depends primarily upon the properties of the market: If it is assumed to be informationally efficient, financial analysis is redundant, but if this is the case, the market cannot be efficient. If, however, the market is assumed to be somewhat inefficient, there will be systematic winners and losers: Being a complex adaptive system, the financial market will exhibit nonlinearities in information. "Information Economics applied to Financial Markets " (Schredelseker) In natural sciences the value of information is always bound from zero: it can never be negative. This does not hold in multiperson-settings like a financial market: Getting better informed may result in a better or in a lower decision quality! A highly skilled and experienced financial analyst is assumed to expect a lower performance in the market as a lousy analyst. Methodology: Game theory, Agent-based modelling, Simulations, Genetic programming. ''Numerical Solutions of Stochastic Differential Equations with Jumps in Finance '' (Platen) In financial and actuarial modelling and other areas of application, stochastic differential equations with jumps have been employed to describe the dynamics of various state variables. The numerical solution of such equations is more complex than that of those only driven by Brownian motions. The aim of this lecture is to present various numerical methods used in quantitative finance for models involving stochastic differential equations with jumps. It emphasises mathematical concepts, techniques and intuition crucial for modern numerical methods in derivative pricing and risk management. Questions of numerical stability and convergence will be discussed. Several recent results will be presented on higher-order methods for scenario and Monte Carlo simulation, including implicit, predictor corrector and extrapolation methods. "A Benchmark Approach to Finance " (Platen) This lecture introduces into the benchmark approach, which provides a generalized framework for financial market modelling. It allows for a unified treatment of derivative pricing, portfolio optimization and risk management. It extends beyond the classical asset pricing theories, with significant differences emerging for extreme maturity contracts and risk measures relevant to pensions and insurance. The Law of the Minimal Price will be presented for derivative pricing. A Naïve Diversification Theorem allows forming a proxy for the numeraire portfolio. The richer modelling framework of the benchmark approach leads to the derivation of tractable, realistic models under the real world probability measure. It will be explained how the approach differs from the classical risk neutral approach. Examples on long term and extreme maturity derivatives demonstrate the important fact that a range of contracts can be less expensively priced and hedged than suggested by classical theory. --- Questa e-mail è priva di virus e malware perché è attiva la protezione avast!

Seminario di Valeria Bignozzi presso Prometeia - Bologna
by Giacomo Scandolo 17 Apr '15

17 Apr '15

Il giorno Giovedì 23 Aprile 2015, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Valeria BIGNOZZI (Università di Firenze) terrà un seminario dal titolo "How superadditive can a risk measure be?" Abstract Risk measures that are not subadditive may penalize the aggregation of risk, by inducing portfolio requirements that are larger than those of undiversified positions. This happens for instance for Value-at-Risk (VaR), as well as convex shortfall risk measures. In this paper we characterize the potential for superadditivity that any risk measure may exhibit, considering both dependence uncertainty as well as the effect of portfolio size. It is shown that for the wide majority of risk measures of use or interest this corresponds to calculating the smallest dominating coherent risk measure (SDCRM). We show that this risk measure often exists and is identified with the notion of extreme-aggregation risk measure introduced in this paper. Explicit results are provided for the class of distortion risk measures, where the SDCRM is again a distortion risk measure and for the class of shortfall risk measures, where the SDCRM is given by an expectile. --- Questa e-mail è priva di virus e malware perché è attiva la protezione avast!

This paper analyzes, given the sequential nature of reviews and the limited feedback of such past reviews, the information content they communicate to future customers. We focus on the informational setting in which customers only observe the sample mean of past reviews, and ask if customers can recover the true quality of the product based on the feedback they observe. We first analyze the benchmark setting, in which customers interpret the mean as the proxy of quality. In such a case, we show that in the long run,the sample mean of review stabilizes and two cases may arise.If customers are relatively homogeneous, then social learning takes place. If customers are sufficiently heterogeneous, then they consistently overestimate the underlying quality of the product in the long run. This bias stems from the selection associated with observing only reviews of customers who purchase. We show, however,that if customers are sophisticated, then there exists a simple quality inference and purchasing rule that corrects for the selection bias and leads to social learning.In addition, we show that the cumulative consumer surplus losses scale with the square root of the number of customers who have considered a purchase to date, which is of the same order as when customers observe the reviews of all preceding customers. In this framework, we also analyze the externality of sophisticated customers on more naïve ones and quantify the impact that manipulated reviews may have.

Santiago Juan Saglietti Universita' di Buenos Aires Titolo: Metastability for small random perturbations of a PDE with blow-up Venerdi' 17 Aprile 2015 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre AULA 311 (SEMINARI) Largo San L. Murialdo,1 Abstract We consider the stochastic PDE $u_t = u_{xx} + u^p + varepsilon dot{W}$ with homogenous Dirichlet boundary conditions, where $p > 1$, $varepsilon > 0$ is a small fixed parameter and $dot{W}$ stands for space-time white noise. It is well known that the associated deterministic PDE (i.e. $varepsilon = 0$ in the equation above) admits exactly one asymptotically stable equilibrium and a countable family of unstable equilibria with increasing energy. Furthermore, for certain initial conditions it can be shown that the solution of the deterministic PDE explodes in finite time. We show that, for $p < 5$ and initial conditions in the domain of attraction of the asymptotically stable equilibrium, the solution $X_varepsilon$ of the SPDE satisfies in the limit as $varepsilon$ tends to zero the classical description of metastability featured in [1]: the averages of $X_varepsilon$ remain stable and close to the equilibrium up until the explosion time which, when suitably rescaled, converges in distribution to an exponential random variable. Furthermore, for certain initial conditions in the domain of explosion (and any value of $p > 1$) we show the continuity of the explosion time as $varepsilon$ tends to zero.

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 10 Aprile 2015 alle ore 12:00, presso la Classroom 4 del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Frédéric LAVANCIER (Université de Nantes) DETERMINANTAL POINT PROCESS MODELS AND STATISTICAL INFERENCE Abstract: In this talk, I will demonstrate that Determinantal point processes (DPPs) provide useful models for the description of repulsive spatial point processes. Such data are usually modeled by Gibbs point processes, where the likelihood and moment expressions are intractable and simulations are time consuming. I will recall the definition of a DPP and review some of these appealing properties which make DPP models well suited for statistical analysis. In particular the ’most repulsive’ DPP will be characterized. Parametric models of DPPs will be introduced, where the likelihood and moment expressions can be easily evaluated and realizations can be quickly simulated. Some illustrations on real datasets will be presented. This work has been carried out in collaboration with Jesper Møller and Ege Rubak, Aalborg University. The study of the repulsiveness of DPPs is part of a joint work with Christophe Biscio, University of Nantes. Tutti gli interessati sono invitati a partecipare.

Seminario di Roy Cerqueti presso Prometeia - Bologna
by Giacomo Scandolo 02 Apr '15

02 Apr '15

Il giorno Giovedì 9 Aprile 2015, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Roy CERQUETI (Università di Macerata) terrà un seminario dal titolo "Markov chains approximation for resampling and bootstrapping" Abstract Markov chain theory is proving to be a powerful approach to resample highly nonlinear time series in the context of bootstrap procedures. In this talk a discussion on this theme is provided, with a special focus on the estimation of the memory of a Markov chain (i.e. its order) and on the identification of its relevant states. In particular, the choice of memory lags and the aggregation of irrelevant states are obtained by looking for regularities in the transition probabilities. At this aim, suitable optimization models are developed under an information theory perspective. More specifically, two competing objectives that a researcher will in general pursue when dealing with bootstrapping are considered: preserving the “structural” similarity between the original and the simulated series and assuring a controlled diversification of the latter. Several critical issues emerge and are analyzed, such as the remarkable complexity of the optimization problem due to the high cardinality of the admissible regions and the presence of interconnections between more than one resampled series in a multivariate framework. Numerical experiments based on real data validate the theoretical treatment of the problem. --- Questa e-mail è priva di virus e malware perché è attiva la protezione avast!

No Free Lunch Seminar by Dr. Joao da Gama Batista, Fri April 10 1:00 PM Aula Bianchi @ SNS

31 Mar '15

Fri April 10 2015, 1:00 PM in Aula Bianchi, Scuola Normale Superiore Pisa Joao da Gama Batista Laboratoire de mathématiques appliquées aux systèmes École Centrale de Paris will deliver the seminar "Sudden trust collapse in networked societies" Abstract: Trust is a collective, self-fulfilling phenomenon that suggests analogies with phase transitions. We introduce a stylized model for the build-up and collapse of trust in networks, which generically displays a first order transition. The basic assumption of our model is that whereas trustworthiness begets trustworthiness, panic also begets panic, in the sense that a small decrease in trustworthiness may be amplified and ultimately lead to a sudden and catastrophic drop of collective trust. We show, using both numerical simulations and mean-field analytic arguments, that there are extended regions of the parameter space where two equilibrium states coexist: a well-connected network where global confidence is high, and a poorly connected network where global confidence is low. In these coexistence regions, spontaneous jumps from the well-connected state to the poorly connected state can occur, corresponding to a sudden collapse of trust that is not caused by any major external catastrophe. In large systems, spontaneous crises are replaced by history dependence: whether the system is found in one state or in the other essentially depends on initial conditions. All interested people are kindly invited.

Seminario di Bernardo Nipoti a Pavia
by Carbone Raffaella 26 Mar '15

26 Mar '15

Cari colleghi, vi annuncio che martedì 31 marzo, alle ore 14 precise, nell'aula Beltrami del Dipartimento di Matematica dell'Universita' di Pavia, Bernardo Nipoti (Dipartimento di Economia e Statistica - Università di Torino) terrà un seminario dal titolo Rediscovery of Good-Turing estimators via Bayesian Nonparametrics Sunto: The problem of estimating discovery probabilities originated in the context of statistical ecology, and in recent years it has become popular due to its frequent appearance in challenging applications arising from biology, bioinformatics, genetics, linguistics, etc. A full range of statistical approaches, parametric and nonparametric as well as frequentist and Bayesian, have been proposed for estimating discovery probabilities. We investigate the relationship between the celebrated Good-Turing approach, which is a frequentist nonparametric approach developed in the 1940s, and the Bayesian nonparametric approach recently introduced in the literature. Specifically, under the assumption of a two parameter Poisson-Dirichlet prior, we show that Bayesian nonparametric estimators of discovery probabilities are asymptotically equivalent to suitably smoothed Good-Turing estimators. As a by-product of this result, we present and discuss a methodology for deriving asymptotic credible intervals to be associated to the Bayesian nonparametric estimators of discovery probabilities.

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Lunedì 30 marzo ore 14 - Aula Belpasso - Dipartimento di Matematica Università di Roma Tor Vergata Speaker: Pierpaolo Brutti, Università "La Sapienza" - Roma Title: Estimating the Intrinsic Dimension: The Bayesian way Abstract: In this talk I will first review some of the methods proposed for making inference on the intrinsic dimension of point cloud data sampled from a low-dimensional structure embedded in a high–dimensional ambient space, and then I will describe a Bayesian solution based on a composite likelihood built under working independence assumptions suggested by MacKay and Ghahramani. In order to get a posterior with approximately correct asymptotic behavior and curvature, I will consider some options to calibrate this pseudolikelihood and then compare in simulated and real examples a standard MCMC method against a variation of the default Bayesian framework of Ventura et al. (2013) (joint work with Alessandro Lanteri). Cordiali saluti Claudio Durastanti

seminario all'IMATI-Milano
by Antonella Bodini 26 Mar '15

26 Mar '15

Mercoledi' 1 aprile alle ore 14 presso la sede di Milano dell'IMATI, via Bassini 15, Sala Pentagonale al secondo piano, Valérie Bélanger dell'Universita' HEC Montréal terra' un seminario dal titolo Analysis and development of real-time ambulance fleet management strategies di cui segue il sunto. Tutti gli interessati sono invitati a partecipare. ____________________________ Sunto: Emergency medical services (EMS) evolve in highly random and dynamic contexts. Indeed, the arrival of emergency calls is uncertain and varies throughout the day, forcing decision makers to adapt their decisions in response to observed changes. Two types of decisions are generally considered in real-time: dispatching and relocation. Dispatching decisions consider the selection of which ambulance to send to an emergency call. Relocation decisions consist in relocating available ambulances throughout the day in response to changes in the system state. Given the situation faced by EMS, the analysis and development of real-time management strategies to ensure a good service to the population is clearly of interest. In a first study, several ambulance relocation strategies are compared, and extensive simulation experiments are reported allowing to analyze the performance of these strategies when they face different level of system workload. Results of this study confirm the relevance of simulation methods to support decision-making in EMS stochastic environment. More importantly, they provide researchers and decisions makers with valuable insights on the use of relocation strategies, including the tradeoff between service level and personnel well-being. In a subsequent study, an innovative real-time ambulance fleet management strategy is proposed. New mathematical models and solution approaches are then developed to deal with both relocation and pre-assignment decisions. Preliminary results show that considering explicitly pre-assignment decisions, which are directly related to dispatching decisions, impact location decisions and can help better predict system performances.

No Free Lunch Seminar by Dott. Tommaso Colozza, Wed April 1 1:00 PM Aula Mancini @ SNS
by Giacomo Bormetti 26 Mar '15

26 Mar '15

Wed April 1 2015, 1:00 PM in Aula Mancini, Scuola Normale Superiore Pisa Tommaso Colozza Dipartimento di Statistica e Matematica Applicata all'Economia - Università di Pisa will deliver the seminar "Supply of public debt and demand for risk premia: a Minskian approach to credit risk" Abstract: Financial stability of EMU countries is managed by policy makers through several key macroeconomic indicators; the market instead monitors creditworthiness with credit risk premia embedded in sovereign yields. A demand-supply approach solves this duality: in a Minskian framework, positive inelastic shifts in debt-to-GDP ratio due to widespread macro-financial distress may lower risk appetites of lenders and increase risk premia, up to default. Time-variating risk appetites justify statistical relevance of debt-to-gdp variation on yields levels; if conveniently decomposed, debt velocity allows also to imply a default probability measure comparable to standard CDS-implied measures.

Seminario ANTONIETTI (RGS & Matematica Applicata)
by Giacomo Aletti 24 Mar '15

24 Mar '15

Con preghiera di diffusione tra tutti i possibili interessati, scusandomi per invii multipli. Cordialmente, Giacomo Aletti -------------- Nell'ambito dei Reading Group Seminars e del Seminario di Matematica Applicata, il giorno lunedì 19 Gennaio 2015, alle ore 14.30, nell'Aula C del Dipartimento di Matematica dell'Universita' degli Studi di Milano, Via C. Saldini, 50, Milano, "Testing spiking neural network cerebellar model in closed-loop: three neurorobotic paradigms" Alberto ANTONIETTI Neuroengineering and medical robotics lab., Politecnico di Milano, ABSTRACT: The cerebellum is involved in a large number of different neural processes, especially in associative learning and in fine motor control. To develop a comprehensive theory of sensorimotor learning and control, it is crucial to determine the neural basis of coding and plasticity embedded into the cerebellar neural circuit and how they are translated into behavioral outcomes in learning paradigms. Learning has to be inferred from the interaction of an embodied system with its real environment, and the same cerebellar principles derived from cell physiology have to be able to drive a variety of tasks of different nature, calling for complex timing and movement patterns. We have coupled a realistic cerebellar spiking neural network with a real robot and challenged it in multiple diverse sensorimotor tasks. Adaptive motor control protocols with acquisition and extinction phases have been designed and tested, including an associative Pavlovian task (Eye blinking classical conditioning), a vestibulo-ocular task and a perturbed arm reaching task operating in closed-loop. A bidirectional long-term plasticity rule implemented at parallel fibers-Purkinje cell synapses modulated the output activity in the deep cerebellar nuclei. In all tasks, the neurorobot learned to adjust timing and gain of the motor responses by tuning its output discharge. It succeeded in reproducing how human biological systems acquire, extinguish and express knowledge of a noisy and changing world. ================= Reading Group Seminars: The Reading Group Seminars (RGS) are organized within an open community of researchers interested in applying up to date mathematical modeling and data analysis approaches to the study of biological systems. The RGS take place at the Math. Department in Milan (via Saldini). Initiatives and updates are published on the website: http://rgs.mat.unimi.it/. -- ------------------------------- Giacomo Aletti, Associate Professor ADAMSS Centre (ex MIRIAM) Advanced Applied Mathematical and Statistical Sciences Department of Mathematics (www.matematica.unimi.it) Via Saldini, 50 20133 Milano, Italy Tel: +39-02-503.16158 Fax:+39-02-503.16090 Cell: +39-340-9739142

Schwartzman & Cheng - 25 MARZO - TOR VERGATA - CICLO SEMINARI PASCAL

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Mercoledi` 25 marzo ore 14 - 16 Aula D'Antoni 1101 Dipartimento di Matematica Università di Roma Tor Vergata Speakers: Armin Schwartzman & Dang Cheng Department of Statistics, North Carolina State University Title: Distribution of the Height of Local Maxima of Gaussian Random Fields Abstract: Let {f(t): t \in T} be a smooth Gaussian random field over a parameter space T, where T may be a subset of Euclidean space or, more generally, a Riemannian manifold. We provide a general formula for the distribution of the height of a local maximum P { f(t_0)>u | t_0 is a local maximum of f(t) } when f is non-stationary. Moreover, we establish asymptotic approximations for the overshoot distribution of a local maximum P { f(t_0)>u+v | t_0 is a local maximum of f(t) and f(t_0)>v } as v \to \infty. Assuming further that f is isotropic, we apply techniques from random matrices theory related to the Gaussian orthogonal ensemble to compute such conditional probabilities explicitly when T is Euclidean or a sphere of arbitrary dimension. Such calculations are motivated by the statistical problem of detecting peaks in the presence of smooth Gaussian noise. Tutti gli interessati sono invitati a partecipare. ................................................................................

Seminario Elena Kosygina
by Mariani, Mauro 17 Mar '15

17 Mar '15

Il giorno Mercoledi' 25 marzo 2015, alle ore 14:00, nell'Aula G del Dipartimento di Matematica dell'Universita' la Sapienza di Roma Elena Kosygina (Baruch College and the CUNY Graduate Center) effettuera' un seminario di circa un'ora: TITOLO: Excited random walks in Markovian cookie environments on Z SUNTO: We consider a nearest-neighbor random walk on Z whose probability ω(x, n) to jump to the right from site x depends not only on x but also on the number of prior visits n to x. The collection (ω(x, n)) is sometimes called the “cookie environment” due to the following informal interpretation. Upon each visit to a site the walker eats a cookie from the cookie stack at that site and chooses the probability to jump to the right according to the “flavour” of the cookie eaten. Assume that the cookie stacks are i.i.d. and that only the first M cookies in each stack may have “flavour”. All other cookies are assumed to be “plain”, i.e. after their consumption the walker makes unbiased steps to one of its neighbours. The “flavours” of the first M cookies within the stack can be different and dependent. We discuss recurrence/transience, ballisticity, and limit theorems for such walks. The talk is based on joint works with Dolgopyat (University of Mary-land), Mountford, Zerner. Tutti gli interessati sono invitati a partecipare Un saluto Mauro Mariani
