Tate-Vogel and relative cohomologies of complexes with respect to cotorsion pairs
Jiangsheng Hu, Huanhuan Li, Jiaqun Wei +2
We study Tate-Vogel and relative cohomologies of complexes by applying the model structure induced by a complete hereditary cotorsion pair ($\A$, $\B$) of modules. We show first th…
Quasi-cotilting modules and torsion-free classes
Peiyu Zhang, Jiaqun Wei
We prove that all quasi-cotilting modules are pure-injective and cofinendo. It follows that the class CogenM is always a covering class whenever M is a quasi-cotilting module. Some…
Cosilting complexes and AIR-cotilting modules
Peiyu Zhang, Jiaqun Wei
We introduce and study the new concepts of cosilting complexes, cosilting modules and AIR-cotilting modules. We prove that the three concepts AIR-cotilting modules, cosilting modul…
Finitistic Dimension Conjecture and Conditions on Ideals
Jiaqun Wei
The notion of Igusa-Todorov classes is introduced in connection with the finitistic dimension conjecture. As application we consider conditions on special ideals which imply the Ig…
Auslander Bounds and Homological Conjectures
Jiaqun Wei
Inspired by recent works on rings satisfying Auslander's conjecture, we study invariants, which we call Auslander bounds, and prove that they have strong relations to some homologi…
