The core-EP inverse: A numerical approach for its acute perturbation

Mengmeng Zhou, Jianlong chen, Nestor Thome

This paper studies the concept of stable perturbation $B \in C^{n \times n}$ for the core-EP inverse of a matrix $A \in C^{n \times n}$ with index $k$ . For a given stab…

m-weak group inverses in a ring with involution

Yukun Zhou, Jianlong Chen, Mengmeng Zhou

In a unitary ring with involution, we prove that each element has at most one weak group inverse if and only if each idempotent element has a unique weak group inverse. Furthermore…

The core and dual core inverses of morphisms with kernels

Tingting Li, Jianlong Chen, Mengmeng Zhou +1

Let $C$ be an additive category with an involution $*$ . Suppose that $φ : X \to X$ is a morphism with kernel $κ : K \to X$ in $C$ , then $φ$ is…

Three limit representations of the core-EP inverse

Mengmeng Zhou, Jianlong Chen, Tingting Li +1

In this paper, we present three limit representations of the core-EP inverse. The first approach is based on the full-rank decomposition of a given matrix. The second and third app…
