Rigid and -locally free modules via Taft algebras
Edmund Heng, Calvin Pfeifer
We show that rigid modules are -locally free for a large family of 1-Iwanaga--Gorenstein algebras. This family includes many cases of the algebras introduced by Geiss--Leclerc--…
Serre cyclotomic algebras
Calvin Pfeifer
We introduce a class of proper differential graded algebras which we call Serre cyclotomic. They generalize fractionally Calabi-Yau algebras and categorify de la Peña's algebras of…
A generic classification of locally free representations of affine GLS algebras
Calvin Pfeifer
Throughout, let be an algebraically closed field of characteristic . We provide a generic classification of locally free representations of Geiss-Leclerc-Schröer's algebras…
Remarks on -tilted versions of the second Brauer-Thrall Conjecture
Calvin Pfeifer
In this short note, we state a stable and a -reduced version of the second Brauer-Thrall Conjecture. The former is a slight strengthening of a brick version of the second Brauer…
