Abstract
A necessary and sufficient condition is derived (in terms of supporting functionals) for a closed convex body in a partially ordered Banach space to possess “Markov's property:” ifa < c < b,a ∈ K, b ∈ K, then c ∈ Int K. Our criterion enables us to express certain analytic results in geometrical form.
