Endomorphism rings via minimal morphisms

Manuel Cortés-Izurdiaga, Pedro A. Guil Asensio, D. Keskin Tütüncü +1

We prove that if $u : K \to M$ is a left minimal extension, then there exists an isomorphism between two subrings, $End_{R}^{M} (K)$ and $End_{R}^{K} (M)$ of $\textrm…

Isomorphism Problem For Uniserial Modules Over An Arbitrary Ring

Gabriella D'Este, Fatma Kaynarca, Derya Keskin Tütüncü

Firstly, we give a partial solution to the isomorphism problem for uniserial modules of finite length with the help of the morphisms between these modules over an arbitrary ring. L…
