In this paper we investigate the fixed point problem for condensing multimaps on locally G-convex spaces instead of the usual locally convex topological vector spaces. We show that every condensing closed self-multimap that has Γ-convex values on a nonempty complete Γ-convex subset of a locally G-convex space has a fixed point. Some fixed point results for condensing multimaps which have lower semicontinuous...
In this paper, we introduce the concept of the strict Kakutani multimap (KKM) property and investigate the fixed point problem for multimaps having this property on almost Γ-convex subsets of locally G-convex uniform spaces. Our new fixed point theorem generalizes the well-known Fan–Glicksberg fixed point theorem and partially extends the Himmelberg fixed point theorem. Its application to minimax...
