Abstract

The χ-function (the Holevo capacity of constrained channel) and the convex closure of the output entropy for arbitrary infinite dimensional channel are considered. The properties of the χ-function and of the convex closure of the output entropy are explored. The applications of the obtained results to the additivity problem and to the theory of entanglement are presented.
