Ziegler Partial Morphisms in additive exact categories
Manuel Cortés-Izurdiaga, Pedro A. Guil Asensio, Berke Kalebogaz +1
We develop a general theory of partial morphisms in additive exact categories which extends the model theoretic notion introduced by Ziegler in the particular case of pure-exact se…

The Schröder-Bernstein problem for Modules
Pedro A. Guil Asensio, Berke Kalebogaz, Ashish K. Srivastava
In this paper we study the Schröder-Bernstein problem for modules. We obtain a positive solution for the Schröder-Bernstein problem for modules invariant under endomorphisms of the…

Modules which are coinvariant under automorphisms of their projective covers
Pedro A. Guil Asensio, Derya Keskin Tütünc\", Berke Kalebogaz +1
In this paper we study modules coinvariant under automorphisms of their projective covers. We first provide an alternative, and in fact, a more succinct and conceptual proof for th…
