Equivalence of categories, Gruson-Jensen duality, and applications
S. Crivei, M. C. Iovanov
For coalgebras over a field, we study when the categories ${}^C\Mm$ of left -comodules and $\Mm^C$ of right -comodules are symmetric categories, in the sense that there i…

Maximal exact structures on additive categories revisited
Septimiu Crivei
Sieg and Wegner showed that the stable exact sequences define a maximal exact structure (in the sense of Quillen) in any pre-abelian category. We generalize this result for weakly…

One-sided exact categories
Silvana Bazzoni, Septimiu Crivei
One-sided exact categories appear naturally as instances of Grothendieck pretopologies. In an additive setting they are given by considering the one-sided part of Keller's axioms d…
