Abstract:

In this paper, we consider the existence and multiplicity of periodic solutions of the problem $u’ + Au \ni g(t,u)$ where $A$ is a subdifferential of a convex function defined in a Hilbert space $H$ and $g:R \times H \to H$ is a Carathéodory function periodic with respect to the first variable.
