SEMINARI CONGIUNTI DI PROBABILITA' - ROMA1 E ROMA3
by Faggionato, Alessandra 19 Jun '15

19 Jun '15

MERCOLEDI' 24 GIUGNO, PRESSO IL DIPARTIMENTO DI MATEMATICA DELLA SAPIENZA, VI SARANNO 2 SEMINARI DI PROBABILITA', CO-ORGANIZZATI DA ROMA1 E ROMA3. Riporto sotto i dettagli Grazie per l'attenzione Alessandra Faggionato Mercoledi' 24 Giugno, ore 14:30 Aula Picone, Dipartimento di Matematica (La Sapienza) Seminario congiunto di Probabilita' (Roma1 e Roma 3) Speaker: Vittoria Silvestri (Cambdrige) Title: Fluctuation results for Hastings-Levitov planar growth Abstract: In 1998 the physicists Hastings and Levitov introduced a family of continuum models to describe a range of physical phenomena of planar aggregation/diffusion. These consist of growing random clusters on the complex plane, which are built by iterated composition of random conformal maps. It was shown by Norris and Turner (2012) that in the case of i.i.d. maps the limiting shape of these clusters is a disc: in this talk I will show that the fluctuations around this shape are given by a random holomorphic Gaussian field F on {|z| > 1}, of which I will provide an explicit construction. When the cluster is allowed to grow indefinitely, I will show that the boundary values of F converge to a distribution-valued Fractional Gaussian Field on the unit circle, which is log-correlated, and critical in a sense that I will explain. **************************************************************************************************************** Mercoledi' 24 Giugno, ore 15:30 Aula Picone, Dipartimento di Matematica (La Sapienza) Seminario congiunto di Probabilita' (Roma1 e Roma 3) Speaker: Oriane Blondel (Lione) Title: Random walk on the East model (and other environments with spectral gap) Abstract: The East model is a one-dimensional interacting particle system with non attractive spin-flip dynamics. In the physics literature, it is a key example of a model with glassy features. Here we take this model as a random environment and investigate the behaviour of a random walk whose jump rates depend on the current configuration. The analysis relies on general results established for random walks in random environment when the environment is Markovian with positive spectral gap. Joint work with Luca Avena and Alessandra Faggionato. -- Prof. Alessandra Faggionato Department of Mathematics University La Sapienza Piazzale A. Moro, 2 00186 Rome - Italy

June 19th 2015, 11.30h Agustin Mayo Iscar talks on Robust Model based clustering
by Francesca Greselin 15 Jun '15

15 Jun '15

On June 19th 2015, 11.30h at Dipartimento di Statistica e Metodi Quantitativi Sala del Consiglio (edificio U7, 4° piano, 4064) Via Bicocca degli Arcimboldi, 8 – 20126 Milano Agustín Mayo-Iscar - Universidad de Valladolid and IMUVA will give a talk on “Robust model-based clustering and mixture modeling by using trimming and restrictions” Abstract The use of trimming procedures is common in many statistical settings to achieve robustness against outlying observations. Notably, to obtain robustness in model-based clustering and mixture modeling, the only adoption of trimming is not enough. Constraints on the scatters, corresponding to the clusters or to the mixture components, are needed too. The talk presents robust methodology based on the joint application of trimming and feasible restrictions for different clusters and mixture models settings. As it is typical in all proposals designed for this aim, some input parameter needs to chosen, to set the trimming level and the scatter constraints. Data driven tools for helping the user in choosing such values will be also presented. for more info: e-mail: francesca.greselin(a)unimib.it http://www.dismeq.unimib.it

Seminario di Elliot Lieb il 16-06-2015 a Roma Tre
by Pietro Caputo 15 Jun '15

15 Jun '15

SEMINARIO Prof. Elliott Lieb Princeton University (with Mathieu Lewin, C.N.R.S.) Titolo: Indirect Coulomb Energy with Gradient Correction Martedi' 16 Giugno 2015 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Aula F, primo piano, edificio Aule Largo San Leonardo Murialdo,1 Abstract We prove a Lieb-Oxford-type inequality on the indirect part of the Coulomb energy (also known as the exchange-correlation energy) of a general many-particle quantum state, with a lower constant than the original statement but involving an additional gradient correction. The result is similar to an inequality of Benguria, Bley and Loss, except that our correction term is purely local, which is more usual for density functional theory. No previous knowledge of the subject will be assumed; a short tutorial on the subject and its importance to quantum chemistry will be presented.

Seminario Prof. Z. Tomovski (presso Dip. Scienze Statistiche, Roma)
by Alessandro Degregorio 12 Jun '15

12 Jun '15

----------------------------------------------------------------------------- A v v i s o d i S e m i n a r i o ----------------------------------------------------------------------------- Martedì 16 Giugno, ore 11 ----------------------------------------------------------------------------- Stanza 34 Dipartimento di Scienze Statistiche "Sapienza" Università di Roma Prof. Z. Tomovski (University of Skopje) Title: *Complete monotonicity of the Mittag-Leffler functions and Opial type inequalities for fractional differential and integral operators involving Mittag-Leffler functions * Abstract: Completely monotonic functions have applications in different areas of mathematics, for instance, in potential theory, probability theory, numerical and asymptotic analysis and combinatorics, modeling by anomalous diffusion, etc. In this talk we'll present some recent new results on complete monotonicity of three parameter Mittag-Leffler functions, defined by Prabhakar. In 1960, Opial established an integral inequality, which is a fundamental result in the theory of differential or difference equations and other areas of mathematics. Opial-type integral inequalities were considered for different kinds of fractional derivatives and fractional integral operators for example Riemann-Liouville, Caputo, Canavati, etc. We'll presents a class of very general weighted Opial type integral inequalities using integral and differential operators with kernels in fractional calculus involving generalized Mittag-Leffler functions. Namely, ineteresting Opial type inequalities will be given for Hilfer, Prabhakar, Hilfer-Prabhakar, Caputo-Prabhakar and other differential and integral operators in fractional calculus. Tutti gli interessati sono invitati a partecipare.
