Abstract

In this paper, are defined the congruence module a compact operator and the invertibility module, a compact operator. Some examples of operators congruent module a compact operator and invertible operators module a compact operator are here presented. Some properties of this congruence are demostrated and these concepts were used to establish a characterization of the Fredholm operators, and some algebraic properties of these operators as well.
