Published in 2018 at "Communications in Algebra"

DOI: 10.1080/00927872.2017.1378895

Abstract: ABSTRACT We define and investigate the e-core inverse and f-dual core inverse in a ring with involution as extensions of the core and dual core inverse, respectively. Using these definitions, we present and characterize the… read more here.

Published in 2019 at "Journal of Mathematics"

DOI: 10.1155/2019/1631979

Abstract: In this paper, we give the direct method to find of the core inverse and its generalizations that is based on their determinantal representations. New determinantal representations of the right and left core inverses, the… read more here.
