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 $(I - P Q)^{†} P (I - Q)$ , $(I - QP)^{†} (I - Q)$ and $P (P + Q - QP)^{†}$ 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 $R$ 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 =…
