Abstract
We prove that a topological space is uniform Eberlein compact iff it is homeomorphic to a super weakly compact subset C of a Banach space such that the closed convex hull co̅C of C is super weakly compact. We also show that a Banach space X is super weakly compactly generated iff the dual unit ball B X* of X* in its weak star topology is affinely homeomorphic to a super weakly compactly convex subset of a Banach space.
