Simultaneous extension of generalized BT-inverses and core-EP inverses

Abdessalam Kara, Néstor Thome, Dragan S. Djordjevi'c

In this paper we introduce the generalized inverse of complex square matrix with respect to other matrix having same size. Some of its representations, properties and characterizat…

Completion problem of upper triangular $3 \times 3$ operator matrices on arbitrary Banach spaces

Nikola Sarajlija, Dragan S. Djordjević

We solve the completion problem of $3 \times 3$ upper triangular operator matrix acting on a direct sum of Banach spaces and hence generalize the famous result of Han, Lee, Lee (Proc…

Group, Moore-Penrose, core and dual core inverse in rings with involution

Dragan S. Rakić, Nebojša Č. Dinčić, Dragan S. Djordjević

Let $R$ 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…
