Abstract

In this paper, we study variational inequalities of the form {⟨A(u),v-u⟩+⟨F(u),v-u⟩+J(v)-J(u)≥0,∀v∈Xu∈X,where A and F are multivalued operators represented by integrals, J is a convex functional, and X is a Sobolev space of variable exponent. The principal term A is a multivalued operator of Leray-Lions type. We concentrate on the case where F is given by a multivalued function f= f(x, u, ∇ u) that depends also on the gradient ∇ u of the unknown function. Existence of solutions in coercive and noncoercive cases are considered. In the noncoercive case, we follow a sub-supersolution approach and prove the existence of solutions of the above inequality under a multivalued Bernstein-Nagumo type condition.
