Buongiorno, Claudio Landim (IMPA, Rio de Janeiro) farà un seminario Martedi' 15 Settembre alle ore 14.00 in Sala di Consiglio del Dipartimento di Matematica G. Castelnuovo alla Sapienza. Sotto titolo e abstract Saluti Alessandra Titolo: Non-equilibrium fluctuations of gradient exclusion processes in dimension [image: d\leq 3] Abstract: We consider a gradient, speed-change, symmetric exclusion process on the discrete torus [image: \mathbb{T}^d_n], [image: d\le 3], whose empirical measure evolves, on the diffusive scale, according to a non-linear parabolic equation. We prove that, starting from a sequence of initial states whose relative entropy with respect to the inhomogeneous product measure associated with the initial profile is [image: o(n^{d/2})], and whose density fluctuation field converges, the density fluctuation field converges, in [image: L^1(0,T; H_{-r})], to the solution of a linear stochastic partial differential equation with time-dependent coefficients driven by a conservative space-time white noise. -- ****************************************************************************** Prof. Alessandra Faggionato https://sites.google.com/mat.uniroma1.it/alessandrafaggionato/home Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 123, first floor ******************************************************************************
