Group, Moore-Penrose, core and dual core inverse in rings with involution
Dragan S. Rakić, Nebojša Č. Dinčić, Dragan S. Djordjević
Let be a ring with involution. The recently introduced notions of the core and dual core inverse are extended from matrix to an arbitrary -ring case. It is shown that the gr…
