On a weighted core inverse in a ring with involution
Dijana Mosić, Chunyuan Deng, Haifeng Ma · Communications in Algebra · 2017
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 e-core partial order and the f-dual core partial order. We describe the sets of all elements a Rickart ∗-ring which are below a given element under the e-core and f-dual core partial order. New characterizations of weighted-EP elements are given too.
