On Banach-Stone type theorems in uniform multiplicative subgroups of C(K)-spaces

Abstract

In this article, we study the preservation properties of (Šilov) boundary of multiplicative subgroups in C(X) spaces for non-surjective norm-preserving multiplicative maps. We also show a sufficient condition for surjective maps between groups of positive continuous functions to be a composition operator.
