18 Apr '18

Il giorno 4 maggio alle ore 14:30 in aula 3014 del Dipartimento di Matematica e Applicazioni dell'Università di Milano-Bicocca, la dottoressa Sophie Hautphenne dell'Università di Melbourne e Politecnico di Losanna, terrà un seminario dal titolo: The probabilities of extinction in a branching random walk on a strip Tutti gli interessati sono invitati a partecipare. Abstract. We consider a class of multitype Galton-Watson branching processes with countably infinite type set X whose mean progeny matrices have a block lower Hessenberg form. For these processes, we derive partial and global extinction criteria. Our approach involves embedding a finite-type explosive Galton-Watson process in a varying environment in the original infinite-type process, and then establishing asymptotic relationships between the two processes. We study the probability of extinction in sets of types A ⊆ X , q(A). In particular, we develop conditions for q(A) to be different from the global and partial extinction probability vectors. We present an iterative method to compute the vectors q(A), and investigate their location in the set of fixed points of the progeny generating vector.

16 Apr '18

AVVISO di SEMINARIO Il giorno 19 Aprile 2018 ore 14:30 nella Aula E del terzo livello del Dipartimento Matematica e Applicazioni, Università di Napoli FEDERICO II, Complesso di Monte Sant'Angelo, Via Cintia, Napoli, il Prof. Claudio Macci del Dipartimento di Matematica, Università di Roma Tor Vergata, terrà un seminario dal titolo: "Asymptotic behavior of some hitting probabilities for sums of IID Gaussian random sets" Abstract: We consider sequences of partial sums of iid Gaussian random sets (with respect to the Minkowski sum) and we study the asymptotic behavior of some hitting probabilities (of suitable sets of $R^d$) for these partial sums. We also illustrate the use of the importance sampling for the estimation of these hitting probabilities by Monte Carlo simulations. We obtain the analog of well-known results for level crossing probabilities of random walks, and we refer to a version of the classical Cramér's Theorem in large deviations for random compact sets existing in the literature. Joint work with Barbara Pacchiarotti. Tutti gli interessati sono invitati a partecipare. -- Enrica Pirozzi Dipartimento di Matematica e Applicazioni Universita' di Napoli FEDERICO II Via Cintia, Monte S.Angelo, 80126, NAPOLI, ITALY Tel. 081 675634 https://www.docenti.unina.it/ENRICA.PIROZZI

The usage of continuous time models allows us to manage irregularly spaced data (for example in financial time series due to weekends, holidays and breaks during the trading hours) without considering any missing data imputation method. Several routines for simulation and estimation are discussed. The flexibility of the package is due to the fact that the user is allowed to choose several parametric L\'evy distributions for the increments. Tutti gli interessati sono invitati a partecipare.

Carissimi, il Dipartimento di Matematica dell'Università di Trento invita gli interessati al seguente seminario: A mean-field model with discontinuous coefficients for interacting neurons *Lunedì 16 aprile 2018* *Luogo*: *Aula seminari (piano terra)* *Dipartimento di Fisica* *Ore*: 15:00 Relatore: - *Giovanni Alessandro Zanco* (IST Wien) Abstract: We propose a new stochastic model for a system of interacting neurons that follow an integrate-and-fire dynamics with interaction that depends on the (random) spatial configuration of neurons and with discontinuous coefficients. We prove strong well-posedness of the resulting system of SDEs and study the mean-field limit as the number of particles tends to infinity. We obtain a Fokker-Planck-type PDE and show that it has a unique weak function-valued solution, obtained as the limit of the laws of the empirical measures for the system of particles. *Referente:* Stefano Bonaccorsi

seminario Silvana Pesenti - 23 aprile 2018
by Emanuela Rosazza 10 Apr '18

10 Apr '18

Si avvisa che il giorno lunedì 23 aprile alle ore 16 presso l’Università di Milano- Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula 4026) si terrà il seguente seminario: Speaker: Silvana Pesenti (Cass Business School, City, University of London) Titolo: “Cascade Sensitivity Measures” Abstract: In risk management, an internal model consists of three elements: (i) a random vector of input risk factors, (ii) a real valued aggregation function, and (iii) the output, which is a random variable obtained by applying the aggregation function to the vector of risk factors. Sensitivity analysis often requires evaluation of changes in the distribution of the output, when the distribution of risk factors is varied with reference to a baseline input distribution. We introduce a novel sensitivity measure termed cascade sensitivity, which quantifies the extent to which small changes (stresses) in an individual risk factor affect the output risk measure. The proposed method captures the direct impact on the output, as well as indirect effects via other risk factors that are dependent with the one being stressed. In this way, the dependence between risk factors is explicitly taken into account. Alternative representations of the cascade sensitivity measure are provided, requiring either knowledge of the aggregation function's gradient or additional evaluations of the model under alternative distributional assumptions. This is of particular interest in applications, where the distribution of the output is typically determined via simulation methods. Furthermore we give a representation of the proposed sensitivity measure that can be calculated from a single simulated sample starting from the baseline model, without the need to simulate under a different model specification or to explicitly study the properties of the aggregation function. This makes the proposed method attractive for practical applications, as is illustrated through numerical examples. Joint work with Pietro Millossovich and Andreas Tsanakas. Tutti gli interessati sono invitati a partecipare. Un saluto cordiale, Emanuela ******************************************************************************************* Emanuela Rosazza Gianin Dipartimento di Statistica e Metodi Quantitativi Università di Milano-Bicocca Edificio U7 – 4° Piano Via Bicocca degli Arcimboldi, 8 20126 Milano Tel. 02 64483208 Fax. 02 64483105 e-mail: emanuela.rosazza1(a)unimib.it *******************************************************************************************

Advanced School on complexity and emergence: second announcement
by elisa mastrogiacomo 10 Apr '18

10 Apr '18

This is the *second** announcement* of the upcoming *Advanced School on complexity and emergence: ideas, methods, with a special attention to economics and finance (CEIM)* The School will be held in the magnificent Villa del Grumello, Como (Italy) along the Lake Como shore on July 22-27, 2018. The main courses will be given by L. Boi (EHESS – Paris), I. Capelli (Università dell’Insubria), I. Ekeland (Ceremade - Universitè Paris-Dauphine), F. Guerra (Sapienza Università di Roma), J. Jost (Max Planck Institute for Mathematics in the Sciences - Leipzig), Florent McIsaac, (Agence Française pour le Développement), F. Patras (Université de Nice Sophia-Antipolis), F. Riedel (Center for Mathematical Economics, Bielefeld University), F. Semboloni (Università degli studi di Firenze), R. Seri (Università dell’Insubria). The potential participants of the School are primarily master and doctorate students of mathematics, information sciences, theoretical physics, and economics, as well as research workers in those areas, who want to enlarge their spectrum of knowledge towards the area of complexity. The aim of the School is to provide these researchers useful instruments from the theory of complex systems, both on the theoretical level and the methodological ones, bridging the present disciplinary gap, and profiting from knowledge and insights from both communities. The School may have some (limited number of) financial supports. Details about the registration, the application for financial support are available at the website http://ceim.lakecomoschool.org/. We would be grateful if you could circulate this announcement among your PhD students, postdocs and colleagues. With our best regards, Sergio Albeverio Elisa Mastrogiacomo Fabio Minazzi Emanuela Rosazza Gianin Stefania Ugolini

Seminario congiunto di Fisica Matematica e Probabilita' a Roma1
by Faggionato, Alessandra 09 Apr '18

09 Apr '18

Mercoledì 18 aprile, ore 16:30, aula di Consiglio, Dipartimento di Matematica, La Sapienza. Speaker: Fabio Toninelli (Université Lyon 1) *Title: Lozenge tiling dynamics and hydrodynamic equation* Abstract: We study a reversible continuous-time Markov dynamics on lozenge tilings of the torus, introduced by Luby et al. Single updates consist in concatenations of n elementary lozenge rotations at adjacent vertices, with rate 1/n. The dynamics can also be seen as a reversible stochastic evolution of a 2+1-dimensional interface. The dynamics is known to enjoy especially nice features: a certain Hamming distance between configurations contracts with time on average and the relaxation time of the Markov chain is diffusive. We present another remarkable feature of this dynamics, namely we derive, in the diffusive time scale, a fully explicit hydrodynamic limit equation for the height function (in the form of a non-linear parabolic PDE). The mobility coefficient μ in the equation has non-trivial but explicit dependence on the interface slope and, interestingly, is directly related to the system’s surface free energy. The derivation of the hydrodynamic limit is based on the so-called H^{-1} method due to Yau and Funaki-Spohn. Based on joint work with Benoit Laslier (Paris 7). -- ************************************************* Prof. Alessandra Faggionato http://www1.mat.uniroma1.it/~faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************

Seminario LISEO
by Matteo Ruggiero 06 Apr '18

06 Apr '18

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 13 Aprile 2018, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Brunero LISEO (Università di Roma La Sapienza) MODELLING PREFERENCE DATA WITH THE WALLENIUS DISTRIBUTION The Wallenius distribution is a generalisation of the Hypergeometric distribution where weights are assigned to balls of different colours. This naturally defines a model for ranking categories which can be used for classification purposes. Since, in general, the resulting likelihood is not analytically available, we adopt an approximate Bayesian computational (ABC) approach for estimating the importance of the categories. We illustrate the performance of the estimation procedure on simulated datasets. Finally, we use the new model for analysing two datasets about movies ratings and Italian academic statisticians' journal preferences. The latter is a novel dataset collected by the authors. This is a joint work with Clara Grazian and Fabrizio Leisen. ------------------------------------------------ Tutti gli interessati sono invitati a partecipare. Il seminario è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto. Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

Seminar by Giacomo Livan, UCL April 19, 2018 11:00 AM @Bologna, Viale Filopanti 5 Aula Studio (ex Sala Biblioteca)
by Giacomo Bormetti 06 Apr '18

06 Apr '18

? Dear all, Thursday April 19, 2018 at 11:00 AM in Aula Studio (ex Sala Biblioteca) 1st floor, Viale Filopanti, 5 Bologna. Giacomo Livan University College London will present Detecting and measuring bias in online platforms: A Network Science approach The last few years have witnessed the rise of the Sharing Economy, a collection of decentralized online platforms whose users exchange knowledge, goods, and resources on a peer-to-peer basis. Sharing Economy platforms are often praised for their meritocratic approach, where all participants, regardless of their gender or ethnicity, receive the same opportunities to emerge through digital peer review mechanisms. Yet, they have recently come under fire due to reports of discriminatory behaviours and manipulations of their reputation systems. This raises an important question: are Sharing Economy platforms fair marketplaces, where all participants operate on a level playing field, or are they large-scale online aggregators of offline human biases? In this talk I will address this question on a number of examples, showing how online platforms can be represented in terms of networks, and how this allows to detect and measure some of the biases that might affect their users' behaviour. In particular, I will present clear evidence of avoidance between users from different ethnic backgrounds on Airbnb, and I will show how user reputation scores are distorted by the widespread practice of reciprocating highly positive ratings in a variety of platforms. I will conclude by discussing how these findings can be used to provide platform design recommendations, aimed at exposing and possibly reducing the biases we detect, in support of a fairer and more inclusive growth of Sharing Economy platforms. ? Feel free to forward this message to anyone who is potentially interested in.

05 Apr '18

Carissimi, il Dipartimento di Matematica dell'Università di Trento invita gli interessati al seguente seminario:Controlled interacting particle systems *martedì 10 Aprile 2018* *Luogo: *Dipartimento di Matematica, via Sommarive, 14 - Povo (TN) - Aula Seminari "-1" *Ore*: 11:45 *Relatore * - *Carlo Orrieri *(Università di Roma la Sapienza) *Abstract:* We want to connect the optimal control of Vlasov-type PDEs with large systems of controlled interacting particles. The main difference towards the classical mean-field theory is the presence of a central planner influencing the dynamic. In order to rigorously develop a limit theory for this problem we employ the concept of Gamma-convergence. We finally discuss some connections with large deviations theory. The talk is mostly based on a joint paper with M. Fornasier, S. Lisini and G. Savare. *Referente*: Stefano Bonaccorsi

Roma Tre 10-04-2018: Hubert Lacoin, Wetting and Layering for Solid-and-Solid
by Pietro Caputo 30 Mar '18

30 Mar '18

SEMINARIO Probabilita' Hubert Lacoin (IMPA, Rio de Janeiro, Brasil) Titolo: Wetting and Layering for Solid-and-Solid Martedi' 10 Aprile 2018 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - AULA 311 Abstract Solid-on-Solid (SOS) was introduced in the early 50s as a simplified model for lattice interfaces. It is believed to display the same low temperature behavior as three-dimensiona systems with phase coexistence while being considerably easier to analyze. The objective of this talk is to present the result we recently obtained for SOS interacting with a solid substrate, which is the problem associated with the following energy functional $$ V(phi)=eta sum_{xsim y}|phi(x)-phi(y)|-sum_{x}left(h{f 1}_{{phi(x)=0}}-infty{f 1}_{{phi(x)<0}} ight), $$ for $(phi(x))_{xin mathbb Z^2}$ (the graph of $phi$ representing the interface). We prove that for eta sufficiently large, there exists a decreasing sequence $(h^*_n(eta))_{nge 0}$, satisfying $lim_{n oinfty}h^*_n(eta)=h_w(eta)$, and such that: (A) The free energy associated with the system is infinitely differentiable on $mathbb R setminus left({h^*_n}_{nge 1}cup h_w( eta) ight)$, and not differentiable on ${h^*_n}_{nge 1}$. (B) For each nge 0 within the interval $(h^*_{n+1},h^*_n)$ (with the convention $h^*_0=infty$), there exists a unique translation invariant Gibbs state which is localized around height $n$, while at a point of non-differentiability, at least two ergodic Gibbs states coexist. The respective typical heights of these two Gibbs states are $n-1$ and $n$. The value $h^*_n$ corresponds thus to a first order layering transition from level $n$ to level $n-1$.

Seminars at Scuola Normale Superiore, 27-28 March 2018, Elisa Alos
by Giulia 23 Mar '18

23 Mar '18

Dear all, Prof. Elisa Alos (Universitat Pompeu Fabra) will hold the two following Seminars. =========================================================================================================================================================================================== On Tuesday, 27 March 2018 — at 11:00 — Room: Aula Fermi: Title : The implied volatility surface in modeling problems Abstract: In the Black-Scholes model, the volatility parameter is constant. But it is well-known that, if we compute this volatility parameter by inverting market option prices, the result (the implied volatility) will depend on the strike price (a variation described graphically as a smile or skew) and on time to maturity. Classical stochastic volatility models, where the volatility is allowed to be a diffusion process, can capture the observed smiles and skews, but they cannot easily explain the term structure. For instance, recent numerical analysis state that the skew slope is approximately $O((T )^{-k})$, for some positive $k$ and where $T$ denotes the time to maturity, while the rate for these stochastic volatility models is $O(1)$. In this talk, we will see how to construct new stochastic volatility models that can describe this phenomena. Towards this end, we will present short-time approximations for the implied volatility skew and smile. The obtained formulas will give us a useful tool to identify the volatilities that can explain this term structure. Based on this approach, some new models have been proposed recently (as, for example, rough volatilities). In this talk we will discuss on the state of the art of this modeling research, and we will discuss the main advantages and disavantages of these new models. =========================================================================================================================================================================================== On Wednesday, 28 March 2018 — at 14:00 — Room: Aula Bianchi Scienze Title : On the link between the Malliavin derivative operator and the implied volatility behaviour Abstract: We use Malliavin calculus techniques to obtain an expression for the short-time behavior of the at-the-money implied volatility skew and smile, in the context of stochastic volatility models. Our analysis does not requiere the volatility to be a diffusion or a Markov process. The obtained results will give us a tool to construct new models that can allow us to explain the empirical term structure of the implied volatility surface (joint works with J. León and J. Vives). =========================================================================================================================================================================================== Fill free to forward this announcement to your colleagues.

Martedì Venerdì 23 Marzo 2018 alle 11:30 in Aula 1BC45 della Torre Archimede presso il Dipartimento di Matematica dell'Università degli Studi di Padova. SPEAKER: Marco Zamparo AFFILIATION: Politecnico di Torino TITLE: Large Deviations Principles in Renewal Theory ABSTRACT: Cramér's theorem provides a large deviations principle for the empirical mean of independent and identically distributed random variables. In this seminar, I establish a generalization of Cramér's theorem for multivariate renewal-reward processes under optimal hypotheses. The way to attack the problem is the following. A large deviations principle is first obtained for renewal processes constrained by the event that one of the renewals occurs at a predetermined time. Then, results are transferred to standard renewal processes by resorting to conditioning. The constrained setting makes it possible to solve the problem by using an argument based on convexity and sub-additivity, which is inspired by the approach of Bahadur and Zabell to derive the modern form of the Cramér's theorem. Interestingly, with a different interpretation of the time coordinate, constrained renewal processes include important models of statistical mechanics, such as the pinning model of polymers and the Poland-Scheraga model of DNA denaturation. These models are briefly reviewed in the seminar. M. Zamparo, Large Deviations in Renewal Theory and Renewal Models of Statistical Mechanics, arXiv:1801.09941.

Seminario ENRICO SCALAS @ UniTo

********************************************************************* SEMINARI DI PROBABILITA' E STATISTICA MATEMATICA DIPARTIMENTO DI MATEMATICA "G. PEANO" UNIVERSITA' DEGLI STUDI DI TORINO ********************************************************************* Lunedì 26 Marzo 2018 alle ore 14:30 in Aula A presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. ENRICO SCALAS (Department of Mathematics, University of Sussex, UK) terrà un seminario dal titolo A STYLIZED MODEL FOR WEALTH DISTRIBUTION Abstract: The recent book by T. Piketty (Capital in the Twenty-First Century) promoted the important issue of wealth inequality. In the last twenty years, physicists and mathematicians developed models to derive the wealth distribution using discrete and continuous stochastic processes (random exchange models) as well as related Boltzmann-type kinetic equations. In this literature, the usual concept of equilibrium in Economics is either replaced or completed by statistical equilibrium. In order to illustrate this activity with a concrete example, we present a stylised random exchange model for the distribution of wealth. We first discuss a fully discrete version (a Markov chain with finite state space). We then study its discrete-time continuous-state-space version and we prove the existence of the equilibrium distribution. Finally, we discuss the connection of these models with Boltzmann-like kinetic equations for the marginal distribution of wealth. This paper shows in practice how it is possible to start from a finitary description and connect it to continuous models following Boltzmann's original research program. https://arxiv.org/abs/1609.08978 Tutti gli interessati sono invitati a partecipare. -- Federico Polito Department of Mathematics University of Torino Via Carlo Alberto, 10 10123, Torino, Italy Email: federico.polito(a)unito.it Tel: +39 011 6702862 Web: www.federicopolito.it
