Seminario di Santiago Juan Saglietti a Roma Tre il 17/04

Santiago Juan Saglietti Universita' di Buenos Aires Titolo: Metastability for small random perturbations of a PDE with blow-up Venerdi' 17 Aprile 2015 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre AULA 311 (SEMINARI) Largo San L. Murialdo,1 Abstract We consider the stochastic PDE $u_t = u_{xx} + u^p + varepsilon dot{W}$ with homogenous Dirichlet boundary conditions, where $p > 1$, $varepsilon > 0$ is a small fixed parameter and $dot{W}$ stands for space-time white noise. It is well known that the associated deterministic PDE (i.e. $varepsilon = 0$ in the equation above) admits exactly one asymptotically stable equilibrium and a countable family of unstable equilibria with increasing energy. Furthermore, for certain initial conditions it can be shown that the solution of the deterministic PDE explodes in finite time. We show that, for $p < 5$ and initial conditions in the domain of attraction of the asymptotically stable equilibrium, the solution $X_varepsilon$ of the SPDE satisfies in the limit as $varepsilon$ tends to zero the classical description of metastability featured in [1]: the averages of $X_varepsilon$ remain stable and close to the equilibrium up until the explosion time which, when suitably rescaled, converges in distribution to an exponential random variable. Furthermore, for certain initial conditions in the domain of explosion (and any value of $p > 1$) we show the continuity of the explosion time as $varepsilon$ tends to zero.

by Alessandra Micheletti 09 Apr '15

09 Apr '15

invio nuovamente l'annuncio, a causa di un piccolo spostamento di orario: *ANNUNCIO DI SEMINARIO* Il *14 aprile alle ore 15.30* nell'aula C del Dipartimento di Matematica, Universita' degli Studi di Milano, via Saldini 50, Milano si terrà un seminario sulla teoria dell'esistenza ed unicità di particolari equazioni integro-differenziali. *Speaker: *Anna Carpio (Universitad Carlos III Madrid) *Title:* *Well posedness of a kinetic model for angiogenesis* *Abstract.* Tumor induced angiogenesis processes including the effect of stochastic motion, branching and merging of blood vessels can be described by coupling an integro-differential kinetic equation of Fokker-Planck type with a reaction-diffusion equation for the tumor induced angiogenic factor (TAF). The chemotactic force field depends on the gradient of the TAF equation contains the first velocity moment (flux of blood vessels). We develop an existence and uniqueness theory for this system under natural assumptions on the initial data. Our theory combines the construction of fundamental solutions for associated linearized problems with comparison principles, sharp estimates of the velocity moments and compactness results for this type of kinetic and parabolic operators. -- ___________________________________________________________ Dr. Daniela Morale Dept.

Seminario all'IAC
by Giovanni Luca Torrisi 08 Apr '15

08 Apr '15

*Martedi' 14 Aprile 2015*, *ore 14:00* Consiglio Nazionale delle Ricerche, Istituto per le Applicazioni del Calcolo "Mauro Picone", Via dei Taurini 19, 00185 Roma Aula Riunioni (II piano) *CLAUDIO DURASTANTI * (Universita' di Roma Tor Vergata) terra' un seminario dal titolo *Normal approximations of linear and nonlinear statistics over the sphere.* ABSTRACT: Our aim is to study quantitative central limit theorems for some linear and nonlinear statistics based on wavelet coefficients evaluated on spherical Poisson processes of arbitrary dimension. This purpose is attained by merging the Stein-Malliavin approach (introduced in the seminal paper by Peccati, Solè, Taqqu and Utzet (2010)) and the properties of the needlets, wavelets over the q-dimensional sphere featuring strong concentration properties in the spatial and frequency domains, introduced in literature by Narcowich, Petrushev, Ward (2006). We will also discuss some examples: the thresholding and the study of variance in nonparametric density estimation framework and the so- called Sobolev tests for uniformity. This is a joint work with Solesne Bourguin, Domenico Marinucci and Giovanni Peccati. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Giovanni Luca Torrisi.
