PhD student Emanuela Gussetti is giving a talk in our Asia-Pacific Analysis and PDE Seminar on

A pathwise stochastic Landau-Lifschitz-Gilbert equation via rough paths in 1D

Abstract:

Using a rough path formulation, we investigate existence, uniqueness and regularity for the stochastic Landau-Lifshitz-Gilbert equation with multiplicative Stratonovich noise on the one dimensional torus. As a main result we show the Lipschitz continuity of the so-called Itô-Lyons map in the energy spaces $L^\infty(0,T;H^k)∩L^2(0,T;H^{k+1})$ for any k ≥ 1. As a consequence we then deduce a Wong-Zakai type result, a large deviation principle for the solution and a support theorem. At the end of the talk, I will discuss some recent results.The talk is based on a joint work with Antoine Hocquet.

Chair: Ben Goldys (The University of Sydney, Australia)

More information and how to attend this talk can be found at the seminar webpage .

Miranda,
