periodic solutions; fixed points; nonlinear evolution problem; pseudo-Laplacian
Summary:
In this paper we prove existence of periodic solutions to a nonlinear evolution system of second order partial differential equations involving the pseudo-Laplacian operator. To show the existence of periodic solutions we use Faedo-Galerkin method with a Schauder fixed point argument.
