Compact convex sets that admit a lower semicontinuous strictly convex function

Abstract

We study the class of compact convex subsets of a topological vector space which admits a strictly convex and lower semicontinuous function. We prove that such a compact set is embeddable in a strictly convex dual Banach space endowed with its weak${}^{\ast }$ topology. In addition, we find exposed points where a strictly convex lower semicontinuous function is continuous.
