Stereotype approximation property for the group algebra ${\mathcal C}^\star(G)$ of measures

Abstract

The stereotype approximation property is formally a stronger condition than the classical approximation property, and because of that the question which spaces possess the stereotype approximation property is quite difficult. In this paper we show that the group algebra ${\mathcal C}^\star(G)$ of measures on a locally compact grop $G$ always has this property.
