Special Session 21: Variational, topological, and set-valued methods for differential problems
Contents
The existence of critical points for a locally Lipschitz continuous functional F on a closed convex set C of a Banch space X is investigated. The problem of finding extra conditions under which critical points for F on C turn out to be critical on X is also addressed. Some applications concerning elliptic variational-hemivariational inequalities are then worked out.
