TTF classes generated by silting modules
Alejandro Argudin-Monroy, Daniel Bravo, Carlos E. Parra
We study the conditions under which a TTF class in a module category over a ring is silting. Using the correspondence between idempotent ideals over a ring and TTF classes in the m…
Combinatorial free chain complexes over quotient polynomial rings
Daniel Bravo
We present a procedure that constructs, in a combinatorial manner, a chain complex of free modules over a polynomial ring in finitely many variables, modulo an ideal generated by q…
Torsion and torsion-free classes from objects of finite type in Grothendieck categories
Daniel Bravo, Sinem Odabaşı, Carlos E. Parra +1
In an arbitrary Grothendieck category, we find necessary and sufficient conditions for the class of -injective objects to be a torsion class. By doing so, we propose a…
Locally type and -coherent categories
Daniel Bravo, James Gillespie, Marco A. Pérez
We study finiteness conditions in Grothendieck categories by introducing the concepts of objects of type and studying their closure properties with respect to short e…
-injective and -flat covers and preenvelopes, and Gorenstein AC-flat covers
Daniel Bravo, Sergio Estrada, Alina Iacob
We prove that, for any , the classes of -injective modules and of -flat modules are both covering and preenveloping over any ring . This includ…
Torsion pairs over -Hereditary rings
Daniel Bravo, Carlos E. Parra
We study the notions of -hereditary rings and its connection to the classes of finitely -presented modules, FP-injective modules, FP-flat modules and -coherent rin…
