Topologically semiperfect topological rings
Leonid Positselski, Jan Stovicek
We define topologically semiperfect (complete, separated, right linear) topological rings and characterize them by equivalent conditions. We show that the endomorphism ring of a mo…
Projective covers of flat contramodules
Silvana Bazzoni, Leonid Positselski, Jan Stovicek
We show that a direct limit of projective contramodules (over a right linear topological ring) is projective if it has a projective cover. A similar result is obtained for …
Flat Mittag-Leffler modules over countable rings
Silvana Bazzoni, Jan Stovicek
We show that over any ring, the double Ext-orthogonal class to all flat Mittag-Leffler modules contains all countable direct limits of flat Mittag-Leffler modules. If the ring is c…
Tilting via torsion pairs and almost hereditary noetherian rings
Jan Stovicek, Otto Kerner, Jan Trlifaj
We generalize the tilting process by Happel, Reiten and Smalø to the setting of finitely presented modules over right coherent rings. Moreover, we extend the characterization of qu…
The countable Telescope Conjecture for module categories
Jan Saroch, Jan Stovicek
By the Telescope Conjecture for Module Categories, we mean the following claim: "Let R be any ring and (A, B) be a hereditary cotorsion pair in Mod-R with A and B closed under dire…
