Terrà un seminario dal titolo:



*“Diffusive limits for stochastic kinetic *

*equtions”*



*Abstract:*

*In this talk, we consider kinetic equations containing random terms.
The kinetic models contain a small parameter and it is well known
that, after scaling, when this parameter goes to zero the limit
problem is a diffusion equation in the PDE sense, ie a parabolic
equation of second order. A smooth noise is added, accounting for
external perturbation. It scales also with the small parameter. It is
expected that the limit equation is then a stochastic parabolic
equation where the noise is in Stratonovitch form. Our aim is to
justify in this way several SPDEs commonly used. We first treat linear
equations with multiplicative noise. Then show how to extend the
methods to nonlinear equations or to the more physical case of a
random forcing term. The results have been obtained jointly with S. De
Moor and J. Vovelle.*
