Contracting the Maximal Points of an Ordered Convex Set

G. R. Burton

The maximal points of a nonempty closed bounded convex set in a reflexive Banach space, relative to an ordering defined by a locally uniformly convex cone, are studied. The set of maximal points is proved to be contractible, and sufficient conditions are found for it to be contractible by a homotopy with the semigroup property, or by the flow of an ordinary differential equation.
