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…
Wide subcategories and lattices of torsion classes
Sota Asai, Calvin Pfeifer
In this paper, we study the relationship between wide subcategories and torsion classes of an abelian length category from the point of view of lattice theory. Motiva…
