Abstract

In this paper we prove the existence of strong solutions for evolution inclusions of the form −\(\dot x\)(t) ∈ ∂ϕ(x(t))+F(t,x)) defined in a separable Hilbert space, where ∂ϕ(·) denotes the subdifferential of a proper, closed, convex function ϕ(·) andF(t,x) is a multivalued nonconvex, nonmonotone perturbation satisfying a general growth condition.
