Then, … WebTheorem A.1.2 (Bipolar theorem). Let C Rn contain 0. Then the bipolar C00 =(C0)0 equals the closed convex hull of C. Proof. It is clear that C00 is a closed, convex set containing C, so the closed convex hull A of C is a subset of C00. Suppose that the converse inclusion does not hold. Then there exists a point x 0 2 C00 that is not in A. By ...

WebJan 20, 2002 · This bipolar theorem then allows identifying the dual optimisation problem and proving that the corresponding optimisation problems are conjugate. ... Proof of … 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.

Polars and the Bipolar Theorem As we have already seen in Example 2, the closure of convex hulls depends only on the interaction between the ambient space and its (topological) dual.
