Fp-projective periodicity
Silvana Bazzoni, Michal Hrbek, Leonid Positselski
The phenomenon of periodicity, discovered by Benson and Goodearl, is linked to the behavior of the objects of cocycles in acyclic complexes. It is known that any flat $\mathsf{Proj…
Covers and direct limits: a contramodule-based approach
Silvana Bazzoni, Leonid Positselski
We present applications of contramodule techniques to the Enochs conjecture about covers and direct limits, both in the categorical tilting context and beyond. In the -tilting-c…
Recollements from Cotorsion Pairs
Silvana Bazzoni, Marco Tarantino
Given a complete hereditary cotorsion pair in a Grothendieck category , the derived category of the exact catego…
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…
On the abelianization of derived categories and a negative solution to Rosicky's problem
Silvana Bazzoni, Jan Stovicek
We prove for a large family of rings R that their lambda-pure global dimension is greater than one for each infinite regular cardinal lambda. This answers in negative a problem pos…
