Abstract

In this note we consider the right unit-duo ring property on the powers of elements, and introduce the concept of {\it weakly right unit-duo} ring. We investigate first the properties of weakly right unit-duo rings which are useful to the study of related studies. We observe next various kinds of relations and examples of weakly right unit-duo rings which do roles in ring theory.

Keywords: weakly right unit-duo ring, right unit-duo ring, group of units, Jacobson radical, Abelian ring, nilpotent element, $\pi$-regular ring, right duo ring, weakly right duo ring, group ring
