Localization in coalgebras. Applications to finiteness conditions
J. Gomez-Torrecillas, C. Nastasescu, B. Torrecillas
The injective right comodules appearing in the minimal injective resolution of a finite-dimensional comodule need not to be of finite dimension or even quasi-finite. The obstructio…

Wide Morita contexts, relative injectivity and equivalence results
N. Chifan, S. Dascalescu, C. Nastasescu
We extend Morita theory to abelian categories by using wide Morita contexts. Several equivalence results are given for wide Morita contexts between abelian categories, widely exten…

On gradings of matrix algebras and descent theory
S. Caenepeel, S. Dăscălescu, C. Năstăsescu
We classify gradings on matrix algebras by a finite abelian group. A grading is called good if all elementary matrices are homogeneous. For cyclic groups, all gradings on a matrix…
