Quillen equivalences for stable categories
Georgios Dalezios, Sergio Estrada, Henrik Holm
For an abelian category we investigate when the stable categories and $\underline{\mathrm{GIn}}\mathrm{j}(\mathcal{…
Phantom covering ideals in categories without enough projective morphisms
Sergio Estrada, Pedro A. Guil Asensio, Sinem Odabasi
We give sufficient conditions to ensure that the ideal of -phantom maps in a locally -presentable exact category is (spe…
Totally acyclic complexes
Sergio Estrada, Xianhui Fu, Alina Iacob
For a given class of modules $\A$, we denote by $\widetilde{\A}$ the class of exact complexes having all cycles in $\A$, and by $dw(\A)$ the class of complexes with all com…
Gorenstein projective precovers
Sergio Estrada, Alina Iacob, Katelyn Yeomans
We prove that the class of Gorenstein projective modules is special precovering over any left GF-closed ring such that every Gorenstein projective module is Gorenstein flat and eve…
