Nonlinear random perturbations of PDEs and quasi-linear equations in Hilbert spaces depending on a small parameter (2208.12867v1)

Abstract: We study a class of quasi-linear parabolic equations defined on a separable Hilbert space, depending on a small parameter in front of the second order term. Through the nonlinear semigroup associated with such equation, we introduce the corresponding SPDE and we study the asymptotic behavior of its solutions, depending on the small parameter. We show that a large deviations principle holds and we give an explicit description of the action functional.
