Uniqueness of best simultaneous approximation and strictly interpolating subspaces

Research output: Contribution to journalArticlepeer-review

Abstract

It is shown that for uniqueness of best simultaneous approximation for bounded sets, the notion of interpolating subspace should be replaced by a stricter one which takes care of the weak* cluster points of the extreme points of the dual ball.
