Bipolar theorem
WebMar 24, 2024 · In functional analysis, the Banach-Alaoglu theorem (also sometimes called Alaoglu's theorem) is a result which states that the norm unit ball of the continuous dual X^* of a topological vector space X is compact in the weak-* topology induced by the norm topology on X. More precisely, given a topological vector space X and a neighborhood V … WebMar 7, 2024 · This shows that A ∘ is absorbing if and only if 〈⋅, y 〉 ( A) is bounded for all , and by Lemma 3.4 (b) the latter property is equivalent to the σ ( E, F )-boundedness of A. . The following result plays a central role and will be used frequently. Theorem 3.6 (Bipolar theorem) Let 〈 E, F 〉 be a dual pair, A ⊆ E. Then.

We formulate the notion of fork-convexity as an analogue to convexity in this setting. As an intermediate step in the proof of our main result we establish a conditional version of the Bipolar theorem. …
