Abstract

In this paper, we show that every element of a DISCRETE MODULE is a sum of two units if and only if its endomorphism ring has no factor ring isomorphic to Z2. We also characterize UNIT SUM NUMBER equal to two for the endomorphism ring of quasi-discrete modules with finite exchange property.
