WebThe classical Bipolar Theorem of functional analysis states that the bipolar D of a subset D of a locally convex vector space is the smallest closed, balanced and convex set containing D. The locally convex structure of the underlying space is of great importance since the proof relies heavily on the Hahn-Banach Theorem.
