I may add that some of my recent research on statistical inference and related topics has tended to originate largely from teaching. In turn, such research energizes my role as a teacher. In this presentation, I will highlight a number of such interesting problems along with their often unassuming origins. In doing so, I will touch upon Student’s t-distributions, multivariate normality, as well as sufficiency, ancillarity, and Basu’s example.

seminario di Maurizia Rossi a Pavia
by Carbone Raffaella 18 Nov '14

18 Nov '14

Cari colleghi, vi annuncio che giovedì 27 novembre, alle ore 14:30 precise, nell'aula Beltrami del Dipartimento di Matematica dell'Universita' di Pavia, la Dott. Maurizia ROSSI (Università di Roma Tor Vergata) terra' un seminario dal titolo *"Quantitative Central Limit Theorems for Nonlinear Functionals of RandomEigenfunctions on $\mathbb S^d$, $d\ge 2$".* Distinti saluti, Raffaella Carbone ----------------- *ABSTRACT* *We investigate Stein-Malliavin approximations for nonlinear functionals of geometric interest for random eigenfunctions on the unit d-dimensional sphere Sd, d ≥ 2. All our results are established in the high energy limit, i.e. as the corresponding eigenvalues diverge. In particular, we prove a quantitative Central Limit Theorem for the ex- cursion volume of Gaussian eigenfunctions; this goal is achieved by means of several results of independent interest, concerning the asymptotic analysis for the variance of moments of Gaussian eigenfunctions, the rates of convergence in various probability metrics for Hermite subordinated processes, and quantitative Central Limit Theo- rems for arbitrary polynomials of finite order or general, square-integrable, nonlinear transforms. Some related issues were already considered in the literature for the 2- dimensional case S2; our results are new or improve the existing bounds even in this special circumstances. Proofs are based on the asymptotic analysis of moments of all order for Gegenbauer polynomials, and make extensive use of the recent literature on so-called fourth-moment theorems by Nourdin and Peccati. This talk is based on the paper Stein-Malliavin Approximations for Nonlinear Func- tionals of Random Eigenfunctions on Sd, joint work with Domenico Marinucci.----------------* Raffaella Carbone, PhD Ricercatore di Probabilità e Statistica Matematica Dipartimento di Matematica dell'Università degli Studi di Pavia

Seminario CATTANI (RGS & Matematica Applicata)
by Giacomo Aletti 17 Nov '14

17 Nov '14

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 24 Novembre 2014, alle ore 14.30, nell'Aula C del Dipartimento di Matematica dell'Universita' degli Studi di Milano, Via C. Saldini, 50, Milano, "Multispecies models for large neural network description" Anna CATTANI, Center for Neuroscience and Cognitive Systems (CNCS), IIT, Rovereto Joint work with Claudio Canuto Abstract: Today modeling large neural network is a topic more relevant than ever. In particular, the set up of computer simulations describing complex networks with a huge number of nodes is a formidable challenge. The intrinsic difficulties concerning the prohibitive computational costs may be handled to some extent by exploiting what we call "multispecies" models. From a mathematical perspective this issue consists in formalizing the PDE-based continuum models which describe the high-density populations inside the network and studying interactions between them and the ODE-based discrete models for each neuron belonging to the low-density populations. In particular, we exploit such an approach to describe the Golgi-Granular cell loop network in the Cerebellum. Each single cell is described by means of the FitzHugh-Nagumo model and both electrical and chemical (excitatory and inhibitory) synapses are taken into account. Several simulations describing interesting phenomena as synchronization and travelling waves have been done. Biological aspects have also been examined in order to provide our work with scientific completeness.

****************************************************** SEMINARI DI PROBABILITA' E STATISTICA DIPARTIMENTO DI MATEMATICA G. PEANO UNIVERSITA' DEGLI STUDI DI TORINO ****************************************************** Venerdì 28 Novembre 2014 alle ore 14:30 in Aula S presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Dott. MICHAEL HINZ (Department of Mathematics, Bielefeld University) terrà un seminario dal titolo CALCULUS, STOCHASTIC PROCESSES AND GEOMETRY WITHOUT SMOOTHNESS Abstract: The talk deals with analysis and stochastic processes on fully singular spaces (i.e. singular at every or almost every point). In the first part we give a brief introduction to the subject which was started in the late eighties and early nineties by Goldstein, Kusuoka, Barlow, Bass, Kigami and others and is now referred to as 'Analysis on fractals'. Markov processes and their energy functionals (Dirichlet forms) play a key role. In the second part we explain some interrelations between stochastic analysis and items of differential geometry, point out some recent results and applications. 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 6702937 Web: www.federicopolito.it

Bicocca Winter School on SINGULAR STOCHASTIC PDEs
by Francesco Caravenna 14 Nov '14

14 Nov '14

RECENT BREAKTHROUGHS IN SINGULAR STOCHASTIC PDEs Bicocca Winter School (2-6 February 2015) The aim of this school is to present some recent breakthroughs in the theory of non-linear stochastic PDEs, that allow to give a rigorous meaning to some important singular equations for which classical methods fail, due to the irregularity of the noise. Examples include the Kardar-Parisi-Zhang (KPZ) equation in 1d, the equation of stochastic quantization in 3d, the parabolic Anderson model in 2d. The school is mainly targeted at PhD students and young researchers. There will be two mini-courses by Massimiliano Gubinelli (Université Paris Dauphine) and Lorenzo Zambotti (Université Pierre et Marie Curie), presenting different approaches but discussing analogous examples. The venue of the school is the Department of Mathematics and Applications of the University of Milano-Bicocca. For more information and for the registration, see the page: http://www.matapp.unimib.it/~fcaraven/spdes2015/ The Organizing Committee Francesco Caravenna, Federica Masiero, Gianmario Tessitore

Seminario Giovanni Jona Lasinio a Roma Tre 18 Novembre

Giovanni Jona-Lasinio Universita' La Sapienza Titolo: Macroscopic fluctuation theory: an introduction and some applications Martedi' 18 Novembre 2014 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre AULA 311 (SEMINARI) Abstract: The macroscopic fluctuation theory, proposed in collaboration with L. Bertini. A. De Sole, D. Gabrielli and C. Landim to study diffusive systems out of equilibrium, developed over the last decade into a powerful tool to solve concrete problems. After discussing the basic ideas I will illustrate some applications among which the existence of phase transitions in the behaviour of fluctuations. Of special interest are the fluctuations of the current in stationary states. New variational principles appear in the thermodynamics of non-equilibrium stationary states.
