Gorenstein analogues of a projectivity criterion over group algebras
Rudradip Biswas, Dimitra-Dionysia Stergiopoulou
We formulate and answer Gorenstein projective, flat, and injective analogues of a classical projectivity question for group rings under some mild additional assumptions. Although t…

Rudradip Biswas, Hongxing Chen, Kabeer Manali Rahul +2
Recently, Amnon Neeman settled a bold conjecture by Antieau, Gepner, and Heller regarding the relationship between the regularity of finite-dimensional noetherian schemes and the e…
