Seminario Zorana Grbac a Padova
by Tiziano Vargiolu 07 Apr '14

07 Apr '14

ANNUNCIO DI SEMINARIO La Prof. Zorana GRBAC dell'Universit? di Parigi-Diderot (VII) terra' il seguente seminario lunedi' 14 aprile alle ore 15.30 in Aula 1BC45 del Dipartimento di Matematica, via Trieste 63, Padova. TITLE: Post-crisis interest rate models driven by Levy processes ABSTRACT: The recent credit crisis and the European sovereign debt crisis have impacted all financial markets and influenced the way derivatives are priced and hedged. In this talk we focus in particular on interest rate derivative models. When considering these models, two major changes with respect to the pre-crisis models should be taken into account. Firstly, a variety of spreads have developed between the rates that had been essentially the same before the crises. This is known as the multiple-curve phenomenon. Secondly, the crises have highlighted the native form of credit risk, namely the counterparty risk, as well as the funding issues. To meet these new modeling requirements, we develop a multiple-curve model, set in the HJM framework and driven by a Levy process. The use of Levy drivers allows an optimal balance between the flexibility needed to calibrate the model jointly to cap and swaption multiple-curve prices on one side, and the low number of Markov factors allowing the computation of counterparty risk and funding adjustments (CVA) on the other side. The pricing formulas in this framework are presented and possible Levy specifications discussed. We proceed with the calibration of the model and finally use the calibrated model as an underlying model for CVA computations. We conclude with a short and illustrative numerical example considering a basis swap. This is joint work with S. Cr?pey, N. Ngor and D. Skovmand ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

de Finetti risk seminar - aprile 2014
by Emanuela Rosazza Gianin 02 Apr '14

02 Apr '14

On behalf of the Scientific Committee of The de Finetti Risk Seminars - on the Mathematical Theory of Economics and Finance in Milano, we are glad to invite you to participate at the "de Finetti Risk Seminar" on April 9, 2014 at 18.00 with the Lecture Equilibrium in risk sharing games COSTANTINOS KARDARAS London School of Economics Abstract: We study equilibrium sharing of investment risk among agents whose random endowments constitute private information. Given the sharing rules that optimally allocate the submitted endowments, we propose a Nash game where agents' strategic choices consist of the endowments to be submitted for sharing. It is proved that the best response problem admits a unique solution (which we call "best endowment response") and differs from the agent's true risk exposure. Then, we proceed in showing that the Nash equilibrium risk sharing admits a finite dimensional characterisation, and that it exists and is unique in the case of two agents. Analysis shows that the game benefits the agents close to risk neutrality, since their expected utilities are higher at the Nash risk sharing equilibrium than the optimal risk-sharing one. (Joint work with Michail Anthropelos.) LOCATION: The seminar will be held on Wedsnesday, April 9, at 18.00 at Sala di rappresentanza, Department of Mathematics, Milano University, Via Saldini 50, Milano. A refreshment will be offered at 17.30. Scientific Committee: Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ. Bocconi) Prof. Massimo Marinacci (Univ.

Ciclo di Seminari - Progetto ERC PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Lunedì 7 aprile ore 14 Aula D'Antoni 1101 Dipartimento di Matematica Università di Roma Tor Vergata Speaker: Jean-Marc Azaïs IMT, Universite de Toulouse, France Title: The tail of the maxima of Gaussian fields on non locally convex sets. Abstract: The Euler Characteristic method or the Rice method give a full expansion of the tail of the maximum of stationary Gaussian fields defined on some regular sets. A key hypothesis is local convexity that means roughly that, by a smooth change of parameterization, the parameter set can be transform in a convex set. In our talk we will present an alternative method that works for general parameter set as fractals sets and permits to obtain a full expansion in dimensions 2 for a large class. Our result will be illustrated by examples that are all new. Tutti gli interessati sono invitati a partecipare. ................................................................................

For such fields, we consider smoothed polynomial transforms, such as those arising from local estimates of angular power spectra and bispectra; we focus on the geometry of their excursion sets, and we study their asymptotic behaviour, in the high-frequency sense. Our main technical tools are recent results on Malliavin calculus and Total Variation bounds for Gaussian subordinated fields by Nourdin and Peccati, and the Gaussian Kinematic Formula by Adler and Taylor, which we shall review briefly in the talk. We put particular emphasis on the analysis of Euler-Poincaré characteristics, which can be exploited to derive extremely accurate estimates for excursion probabilities. The present analysis is motivated by the statistical investigation of asymmetries and anisotropies in Cosmic Microwave Background radiation (CMB) data. Based on joint work with Sreekar Vadlamani Part II: Stein-Malliavin Approximations for Needlets Polyspectra Valentina Cammarota We provide quantitative Central Limit Theorems, in the high frequency limit, for nonlinear transforms of spherical wavelets/needlets random fields, which are of immediate interest for spherical data analysis. In particular, we focus on so-called needlets polyspectra, which are popular tools for nonGaussianity analysis in the cosmological community, and on the area of excursion sets. Our results are based on Stein-Maliavin approximations for nonlinear transforms of Gaussian fields, and on an explicit derivation on the high-frequency limit of the fields' variances, which may have some independent interest. Based on joint work with Domenico Marinucci Part III: Normal Approximations for Linear and U-Statistics on Spherical Poisson Fields Claudio Durastanti We review a recent stream of research on Normal approximations for linear and U-statistics of wavelets/needlets coefficients evaluated on a homogeneous spherical Poisson fi...eld. We show how exploting results from Peccati and Zheng (2011), based on Malliavin calculus and Stein''s methods, it is possible to assess the rate of convergence to Gaussianity for a triangular array of statistics with growing dimensions. These results can be exploited in a number of statistical applications, such as spherical density estimations, searching for point sources, estimation of variance and the spherical two-sample problem. Based on joint work with Solesne Bourguin, Domenico Marinucci and Giovanni Peccati.

Seminario di Guido Montorsi (Roma - 11 aprile)

Seminari MoMA www.mat.uniroma1.it/ricerca/seminari/moma Venerdi’ 11 aprile, ore 12-14, aula Consiglio Guido Montorsi Analog Digital Belief Propagation and its application to channel decoders Sunto As required by information theory, channel codes with long code words are necessary building blocks in a transmission system to achieve reliable communications with minimal power and maximal throughputs over noisy physical channels. Nowadays capacity-achieving large random binary codes are actually adopted in most telecommunication standards. The breakthrough that allowed their practical use has been to substitute the optimal maximum likelihood decoding techniques at the receiver with suboptimal iterative techniques based on “belief” propagation. Belief propagation is a powerful inference technique working on graphs used in many different applications. Graph nodes are associated to factors or constraints of the model while graph edges are associated to random variables. Belief propagation algorithm proceeds by iteratively updating messages associated to the random variables, according to the constraints imposed by nodes. In the framework of channel decoding the graph nodes represent the deterministic, usually linear, code constraints. They are either associated to a (binary) parity check sum, or to a repetition of the variable. Belief propagation is initialized with a set of messages obtained from the noisy channel observations of the transmitted bits and proceeds iteratively, updating the messages according to the code constraints until convergence is reached. Most practically used codes are linear and binary codes, so that messages propagated in the graph are binary messages usually represented with a single scalar (the Log-Likelihood Ratio). In order to increase the throughput of communication systems, the use of non binary codes is an attractive solution as each symbol can carry more information bits. Non binary codes can be constructed over groups, rings, or fields and there is a vast literature on the design of capacity achieving non binary codes. The extension of the application of belief propagation to the non binary codes however poses several complexity problems as both message representation and message updating at check node grows at least linearly with the cardinality of the non binary alphabet and consequently exponentially with the increase of required throughput. In this talk I will start by recalling the fundamental ideas and terminology beyond binary channel coding constructions and corresponding iterative decoding with belief propagation and other iterative techniques. I will then extend the concepts to non binary codes and summarize the main algorithms and complexity problems related with them. I will then introduce a new algorithm, named Analog Digital Belief Propagation (ADBP) which solves the complexity problems of belief propagation for non binary codes. I will discuss the main properties of the algorithm, its possible extensions and code design problems related to the adoption of this algorithm.

Il giorno Mercoledì 9 Aprile, alle ore 17 [ rinfresco ore 16:45 ] presso il Dipartimento di Informatica Università degli studi di Verona , strada le Grazie 15, Verona Lucian Maticiuc "G. Asachi" Technical University, Romania terrà un seminario dal titolo Stochastic Differential Delay Systems and Optimal Control Problems *Abstract* We show the existence and the uniqueness of the solution for some multivalued stochastic differential equation with delay (the multivalued term is of subdifferential type). Afterwards we consider optimal control problems where the state X is a solution of a controlled delay stochastic system as above. We establish the dynamic programming principle for the value function and finally we prove that the value function is a viscosity solution for a suitable Hamilton- Jacobi-Bellman type equation. __ Luca Di Persio - PhD assistant professor of Probability and Mathematical Finance Dept.
