On Parabolic Variational Inequalities with Multivalued Terms and Convex Functionals

Abstract

In this paper, we consider the following parabolic variational inequality containing a multivalued term and a convex functional: Find u ϵ Lp(0, T;W1,p0 (Ω)) and f ϵ F(., ., u) such that u(., 0) = u0 and (ut + Au, v - u) + ψ(v) - ψ(u) ≥ ∫ Q f(v - u) dx dt for all v ϵ Lp(0, T;W1,p0 (Ω)), where A is the principal term; F is a multivalued lower-order term; ψ(u) = ∫T0 ψ(t, u) dt is a convex functional. Moreover,we study the existence and other properties of solutions of this inequality assuming certain growth conditions on the lower-order term F.
