Abstract
The purpose of this paper is to provide a characterization of locally -convex modules induced by a family of -seminorms using the gauge function for -modules and discussing the notion of countable concatenation. Taking advantage of these ideas we will give a counterexample of a locally -convex topology not induced by any family of -seminorms.
