Hochschild cohomology and support varieties for tame Hecke algebras
Sibylle Schroll, Nicole Snashall
We give a basis for the Hochschild cohomology ring of tame Hecke algebras. We then show that the Hochschild cohomology ring modulo nilpotence is a finitely generated algebra of Kru…

Rhombus Filtrations and Rauzy Algebras
Alex Clark, Karin Erdmann, Sibylle Schroll
Peach introduced rhombal algebras associated to quivers given by tilings of the plane by rhombi. We develop general techniques to analyse rhombal algebras, including a filtration b…

Weight 2 blocks of general linear groups and modular Alvis-Curtis duality
Sibylle Schroll, Kai Meng Tan
We obtain the structure of weight 2 blocks and [2:1]-pairs of q-Schur algebras, and compute explicitly the modular Alvis-Curtis duality for weight 2 blocks of finite general linear…
