On copositive approximation in some classical spaces of sequences

Research output: Contribution to journalArticle

Abstract

In this paper the author writes a simple characterization for the best copositive approximation in c1 the space of convergent sequences, by elements of finite dimensional Chebyshev subspaces, and shows that it is unique.
