Abstract


In this paper, we characterize SEP elements and GSEP elements by various methods. SEP elements are mainly characterized by a element in a given set, and then extended to GSEP elements. GSEP elements are characterized by (b,c)-inverse, inner invertible elements and equations. We obtain a lot of new characterizations of SEP elements, GSEP elements.
