Time dependent evolution inclusions governed by the difference of two subdifferentials

Abstract : The purpose of this paper is to study evolution inclusions involving time depen-dent subdifferential operators which are non-monotone. More precisely, we study existence of solutions for the following evolution equation in a real Hilbert space X : u ′ (t) + ∂f t (u(t)) − ∂ϕ t (u(t)) ∋ w(t), u(0) = u 0 , where f t and ϕ t are closed convex proper functions on X.
