On the proximinality of Stone-Weierstrass subspaces

Jaroslav Mach

Vol. 99 (1982), No. 1, 97–104
Abstract

Let S be a compact Hausdorff space, X a Banach space, C(S,X) the Banach space of all continuous X-valued functions on S equipped with the supremum norm. In this paper a necessary and sufficient condition on X for every Stone-Weierstrass subspace of C(S,X) to be proximinal is established. Furthermore, it is shown that every such subspace is proximinal if X is a dual locally uniformly convex space.
