SEMINARIO DI PROBABILITA' E FISICA STATISTICA Giovedi' 7 Maggio, ore 14.30 , in Aula B (Dipartimento di Matematica. Univ.La Sapienza, Roma) Speaker: Andrea Puglisi (Istituto dei Sistemi Complessi, Sapienza) Title: Dynamics of an intruder in a granular fluid: from dilute to dense experiments. A single experimental setup is the occasion for a tour into many issues in non-equilibrium statistical mechanics. In the experiment, a rotating intruder performs a Brownian-like dynamics under the influence of collisions with a shaken granular media. Dissipations in the form of inelastic collisions and dry tangential friction make the system inherently out of equilibrium. When the granular medium is diluted, the results agree with a Boltzmann-Lorentz description which, in the large mass limit, is well approximated by a Fokker-Planck equation for a Ornstein-Uhlenbeck process with Coulomb friction. When the intruder is shaped so as to break the symmetry under rotation-inversion, an average drift ("ratchet" or "motor" effect) is observed, with properties depending on the dominant dissipation: friction or inelastic collisions. When the density of the surrounding medium increases, non-Markovian effects appear. The first consequence is a violation of the Einstein relation which - near equilibrium - describes the linear response to a small force provided by an external motor. The analysis of a generalized flctuation-dissipation relation explains the nature of the violation: a joint effect of dissipation and coupling with the dense flid. When the density is increased further and the jamming transition is approached, anomalous diffusion appears in the form of transient cage effects (subdiffusion) and - more surprisingly - superfdiffusion at large times. -- Prof. Alessandra Faggionato Department of Mathematics University La Sapienza Piazzale A.

Fwd: Annuncio Seminario Vlad Bally - 27 Aprile - Tor Vergata
by Claudio Durastanti 24 Apr '15

24 Apr '15

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Lunedì 27 aprile - ore 14 - aula D'Antoni Speaker Vlad Bally, Universite' Paris-Est LAMA, INRIA title: Convergence and regularity of probability laws by using an interpolation method Abstract: In a recent paper, Fournier and Printems establish a methodology which allows to rove the absolute continuity of the law of the solution of some stochastic equations with Holder continuous coefficients. This is of course out of reach by using already classical probabilistic methods based on Malliavin calculus. In this context, Debussche and Romito employ some Besov space technics in order to substantially improve the result of Fournier and Printems. In this talk we show that this kind of problem naturally fits in the framework of interpolation spaces: we prove an interpolation inequality which allows to state (and even to slightly improve) the above absolute continuity result. Moreover it turns out that the above interpolation inequality has applications in a completely different framework: we use it in order to estimate the error in total variance distance in some convergence theorems. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Claudio Durastanti

Two seminars and presentation of Ph.D. thesis, Friday April 24
by Tiziano Vargiolu 21 Apr '15

(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!
