Seminario di Probabilità e Finanza Matematica

Mercoledì 29 Maggio 2013 alle ore 15:30 in Aula 1BC45 la Prof.ssa Hakima Bessaih dell'Università del Wyoming terrà un seminario intitolato "Large deviations and the zero viscosity limit for 2D stochastic Navier Stokes equations".

Abstract
Using a weak convergence approach, we prove a LPD for the solution of 2D stochastic Navier Stokes equations when the viscosity converges to 0 and the noise intensity is multiplied by the square root of the viscosity. Unlike previous results on LDP for hydrodynamical models, the weak convergence is proven by tightness properties of the distribution of the solution in appropriate functional spaces.
