Presentations of Schur and Specht modules in characteristic zero
Mihalis Maliakas, Maria Metzaki, Dimitra-Dionysia Stergiopoulou
New presentations of Specht modules of symmetric groups over fields of characteristic zero have been obtained by Brauner, Friedmann, Hanlon, Stanley and Wachs. These involve genera…
Finiteness criteria for Gorenstein homological dimension and some invariants of groups
Ilias Kaperonis, Dimitra-Dionysia Stergiopoulou
In this paper, we study finiteness criteria for the Gorenstein homological dimension of groups over a commutative ring of finite Gorenstein weak global dimension and provide estima…
On stability and nonvanishing of homomorphism spaces between Weyl modules
Charalambos Evangelou, Mihalis Maliakas, Dimitra-Dionysia Stergiopoulou
Consider the general linear group defined over an infinite field of positive characteristic . We denote by the Weyl module of which corresponds to a…
Gorenstein modules and dimension over large families of infinite groups
Dimitra-Dionysia Stergiopoulou
We give characterizations of Gorenstein projective, Gorenstein flat and Gorenstein injective modules over the group algebra for large families of infinite groups and show that ever…
Finiteness criteria for Gorenstein flat dimension and stability
Ilias Kaperonis, Dimitra-Dionysia Stergiopoulou
Projectively coresolved Gorenstein flat modules were introduced recently by Saroch and Stovicek and were shown to be Gorenstein projective. While the relation between Gorenstein pr…
Projectively coresolved Gorenstein flat dimension of groups
Dimitra-Dionysia Stergiopoulou
In this paper, we introduce and study the projectively coresolved Gorenstein flat dimension of a group over a commutative ring and we prove that this dimension enjoys all t…
