New results on EP elements in rings with involution
Long Wang, Dijana Mosic, Yuefeng Gao
In this paper, we mainly give characterizations of EP elements in terms of equations. In addition, a related notion named a central EP element is defined and investigated. Finally,…
Right core inverse and the related generalized inverses
Long Wang, Dijana Mosic, Yuefeng Gao
In this paper, we introduce the notion of a (generalized) right core inverse and give its characterizations and expressions. Then, we provide the relation schema of (one-sided) cor…
Characterizations of the -inverse in a ring
Long Wang, Jianlong Chen, Nieves Castro-González
Let be a ring and . In this paper, we give some characterizations of the -inverse, in terms of the direct sum decomposition, the annihilator and the invertibl…
Projections and Idempotents in star-reducing Rings Involving the Moore-Penrose Inverse
Xiaoxiang Zhang, Shuangshuang Zhang, Jianlong Chen +1
In [Comput. Math. Appl. 59 (2010) 764-778], Baksalary and Trenkler characterized some complex idempotent matrices of the form , and in…
Moore-Penrose Invertibility of Differences and Products of Projections in Rings with Involution
Xiaoxiang Zhang, Shuangshuang Zhang, Jianlong Chen +1
This article concerns the MP inverse of the differences and the products of projections in a ring with involution. Some equivalent conditions are obtained. As applications, the…
Additive Property of Drazin Invertibility of Elements
Long Wang, Huihui Zhu, Xia Zhu +1
In this article, we investigate additive properties of the Drazin inverse of elements in rings and algebras over an arbitrary field. Under the weakly commutative condition of $ab =…
