WebTherefore, the unit ball of such an algebra does not contain any nontrivial compact faces. In the third section, we study the presence of compact faces in the unit ball of a free semigroup algebra.

Web5 dec. 2024 · It is a well known result in functional analysis that a Banach space X is reflexive if and only if the unit ball is weakly compact (compact in the weak topology). This result is also known as Kakutani's theorem. However so far to my knowledge all the proofs for this theorem use in a way or another the Banach-Alaoglu theorem.
