********************************************************************* SEMINARI DI PROBABILITA' E STATISTICA MATEMATICA DIPARTIMENTO DI MATEMATICA "G. PEANO" UNIVERSITA' DEGLI STUDI DI TORINO ********************************************************************* Giovedì 7 Febbraio 2019 alle ore 15:00 in Aula S presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. *Gianni Pagnini* (BCAM – Basque Center for Applied Mathematics, Bilbao, Spain) terrà un seminario dal titolo *Convergence of linear superposition of Langevin-driven Brownian particles **to the fractional Brownian motion* Abstract: A heterogeneous ensemble of Brownian particles governed by the Langevin equation is considered. The heterogeneity of the ensemble is characterised by a population of friction coefficients. When the frequency histogram of the friction coefficients decreases with a proper power-law, the linear superposition of these Brownian trajectories converges to the fractional Brownian motion. This construction of the fractional Brownian motion provides a dynamical framework that allows for physical perspectives. In this respect, this results is first connected with the so-called generalized gray Brownian motion and later the application for modelling anomalous diffusion in biological systems is discussed. The first part of the seminar is based on a research in collaboration with Mirko D'Ovidio whose results are still work in progress, and the second part is based on: M. D'Ovidio, S. Vitali, V. Sposini, O. Sliusarenko, P. Paradisi, G. Castellani, G.

Seminario di Giovanni Luca Torrisi a Bologna
by Alberto Lanconelli 21 Jan '19

21 Jan '19

Statistics Seminars 2019 Mercoledì 6 febbraio ore 14.30 Aula seminari - Dipartimento di Scienze Statistiche, I piano “The Clark-Ocone formula and the Poincare' inequality for point processes” Dr. Giovanni Luca Torrisi, CNR-Istituto per le Applicazioni del Calcolo “M. Picone” (Roma) Abstract: "Clark-Ocone formulas are powerful results in stochastic analysis with a variety of applications. In the talk we provide the Clark-Ocone formula for square-integrable functionals of point processes with stochastic intensity. Then we present two applications of the formula: the Poincare' inequality and a concentration bound for those functionals. Our results generalize the corresponding ones on the Poisson space. The talk is based on joint works with Ian Flint and Nicolas Privault (NTU, Singapore)."

Workshop "The Geometry of Random Fields" Tor Vergata
by Domenico Marinucci 18 Jan '19

18 Jan '19

Cari Colleghi Venerdì 25 gennaio si terrà presso il Dipartimento di Matematica dell'Università di Roma Tor Vergata (Aula D'Antoni) il mini-workshop "The Geometry of Random Fields"; il programma è il seguente: 9.30-10.15 Dmitry Belyaev (Oxford University) Geometry of smooth Gaussian fields and percolation Abstract: Gaussian fields and their level sets are of significant mathematical interest, but they also appear in many other areas of science: oceanography, cosmology and engineering, just to name a few. In this talk I will give an gently introduction to the geometric theory of smooth Gaussian fields, will discuss conjectures about their connection with percolation models and will talk about recent progress in this area. 10.15-11.00 Igor Wigman (King's College London) Points on nodal lines with given direction Abstract: We study of the directional distribution function of nodal lines for eigenfunctions of the Laplacian on a planar domain. This quantity counts the number of points where the normal to the nodal line points in a given direction. We give upper bounds for the flat torus, and compute the expected number for arithmetic random waves. 11.00-11.30 Coffee Break 11.30-12.15 Anne Estrade (Université Paris Descartes) On Berry's dislocation lines in 3D framework Abstract: We study the length of dislocation lines that are given as nodal lines of a complex Gaussian random wave indexed by $\R^3$. We consider random waves that are eigenfunction of the 3D Euclidean Laplacian, isotropically distributed or not. We are particularly interested in the expectation and the variance of the length and their behavior as the associated eigenvalue goes to infinity. We compare the results with the similar situation in 2D that has been extensively studied since Berry's paper in 2002. This is a work in progress with Federico Dalmao and Jose Leon (Universidad de la Republica, Uruguay). 12.15- 13.00 Maurizia Rossi (Università di Pisa) Title: Nodal lengths of random spherical harmonics. Abstract: Random spherical harmonics are Gaussian eigenfunctions of the spherical Laplacian; in this talk we study the geometry of their excursion sets, in particular the high-energy behavior of their boundary length. For the nodal case we show that the length is asymptotically equivalent, in the L^2-sense, to the sample trispectrum, obtaining as a by-product a quantitative Central Limit Theorem for it. The length at non-zero level, being asymptotically equivalent to the (random) norm of the eigenfunction, is proved to be Gaussian and independent of the nodal length in the high-energy limit. Removing the effect of the eigenfunctions norm (which play no role in the nodal case indeed) we prove that the partial correlation between nodal and boundary lengths is asymptotically one. This talk is based on joint works with D. Marinucci and I. Wigman.

Summer school + Workshop on Chemical Reaction Networks Torino 24 June - 3 July 2018
by Enrico Bibbona 17 Jan '19

17 Jan '19

Dear colleagues, I'm organising a summer school and a Workshop on Chemical Reaction Networks in Torino, Italy, form June 24 to July 3rd 2019. I kindly ask you if you are interested in participating and to advertise those events to all the people you know that could be interested, in particular to the youngest. The events are described at the following link https://areeweb.polito.it/disma-excellence/CRNs/Index.html and a summary of the main informations follows. School (June 24-28 2019): It is intended for Master students, PhD and post Doc in Mathematics, Physics, Computer Science, Biology, Statistics, Engineering... More senior attendants are welcome as well. Two courses are organised, the instructors are Carsten Wiuf (Copenhagen University) and Greg Rempala (Ohio State University), and they will cover the theory of CRNs (both stochastic and deterministic) and some applications to molecular biology and epidemiology, including statistical inference. The school will be held in Pracatinat, a tiny mountain hamlet in the Chisone Valley not far from Torino. There is no registration fee, local expenses for a limited amount of early booking participants are covered by the organisation (these participants need to cover only their travel expenses). Workshop (July 1-3 2019) It is located at Politecnico di Torino, and will adress both stochastic and deterministic CRNs, modelling and inference. There is no registration fee, but participants are asked to cover their own expenses (we have limited funding for a few motivated exceptions). Whoever is interested in presenting a talk is welcome to preregister at the conference website.
