 renstein analogues of a projectivity criterion over group algebras</a>\nby
  Dimitra-Dionysia Stergiopoulou (University of Thessaly) as part of Greek 
 Algebra & Number Theory Seminar\n\n\nAbstract\nI will talk about a recent 
 preprint where we formulated and answered Gorenstein projective\, flat\, a
 nd injective analogues of a classical projectivity question for group ring
 s under some mild additional assumptions. Although the original question\,
  that was proposed by Jang-Hyun Jo in 2007\, was for integral group rings\
 , in our paper\, we dealt with more general commutative base rings. We mad
 e use of the developments that have happened in the field of Gorenstein ho
 mological algebra over group rings in recent years\, and we managed to imp
 rove and generalize several existing results from this area along the way.
  Joint work with Rudradip Biswas.\n
