Existence of solution for a generalized stochastic Cahn-Hilliard equation on convex domains. Abstract. We consider a generalized Stochastic Cahn-Hilliard equation with multiplicative white noise posed on bounded convex domains in R d , d = 1, 2, 3, with piece-wise smooth boundary, and introduce an additive time dependent white noise term in the chemical potential. Since the Green's function of the problem is induced by a convolution semigroup, we present the equation in a weak stochastic

... l formulation and prove existence of solution when d ≤ 2 for general domains, and for d = 3 for domains with minimum eigenfunction growth, without making use of any explicit expression of the spectrum and the eigenfunctions. The analysis is based on stochastic integral calculus, Galerkin approximations and the asymptotic spectral properties of the Neumann Laplacian operator. Existence is also derived for some non-convex cases when the boundary is smooth. 2000 Mathematics Subject Classification. 35K55, 35K40, 60H30, 60H15.
