Characterizations of weighted core inverse in rings with involution

Tingting Li

$R$ is a unital ring with involution. We investigate the characterizations and representations of weighted core inverse of an element in $R$ by idempotents and units. For example,…

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…

The core and dual core inverse of a morphism with factorization

Tingting Li, Jianlong Chen

Let $C$ be a category with an involution $*$ . Suppose that $φ : X \to X$ is a morphism and $(φ_{1}, Z, φ_{2})$ is an (epic, monic) factorization of $φ$ through $Z$ ,…

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…
