A generic classification of locally free representations of affine GLS algebras

C Pfeifer - Journal of Algebra, 2025 - Elsevier
Throughout, let K be an algebraically closed field of characteristic 0. We provide a generic
classification of locally free representations of Geiß-Leclerc-Schröer's algebras HK (C, D, Ω) …

Remarks on -tilted versions of the second Brauer-Thrall Conjecture

C Pfeifer - arXiv preprint arXiv:2308.09576, 2023 - arxiv.org
In this short note, we state a stable and a $\tau $-reduced version of the second Brauer-
Thrall Conjecture. The former is a slight strengthening of a brick version of the second …

Semistable torsion classes and canonical decompositions in Grothendieck groups

S Asai, O Iyama - Proceedings of the London Mathematical …, 2024 - Wiley Online Library
We study two classes of torsion classes that generalize functorially finite torsion classes, that
is, semistable torsion classes and morphism torsion classes. Semistable torsion classes are …

Schurian‐finiteness of blocks of type AA Hecke algebras

S Ariki, S Lyle, L Speyer - Journal of the London Mathematical …, 2023 - Wiley Online Library
For any algebra AA over an algebraically closed field FF, we say that an AA‐module MM is
Schurian if End A (M)≅ F End_A(M)≅F. We say that AA is Schurian‐finite if there are only …

The category of a partitioned fan

M Kaipel - Journal of the London Mathematical Society, 2025 - Wiley Online Library
In this paper the notion of an admissible partition of a simplicial polyhedral fan is introduced
and the category of a partitioned fan is defined as a generalisation of the τ τ‐cluster …

τ-tilting Finiteness of Biserial Algebras

K Mousavand - Algebras and Representation Theory, 2023 - Springer
We compare the notions of τ-tilting finiteness and representation-finiteness of the biserial
algebras. In particular, we treat the minimal representation-infinite biserial algebras and give …

A 𝜏-tilting approach to the first Brauer-Thrall conjecture

S Schroll, H Treffinger - Proceedings of the American Mathematical Society, 2022 - ams.org
In this paper we study the behaviour of modules over finite dimensional algebras whose
endomorphism algebra is a division ring. We show that there are finitely many such modules …

MINIMAL (-) TILTING INFINITE ALGEBRAS

K Mousavand, C Paquette - Nagoya Mathematical Journal, 2023 - cambridge.org
Motivated by a new conjecture on the behavior of bricks, we start a systematic study of
minimal-tilting infinite (min--infinite, for short) algebras. In particular, we treat min--infinite …

-Tilting finiteness of group algebras of semidirect products of abelian -groups and abelian -groups

N Hiramae, Y Kozakai - arXiv preprint arXiv:2405.10021, 2024 - arxiv.org
Demonet, Iyama and Jasso introduced a new class of finite dimensional algebras, $\tau $-
tilting finite algebras. It was shown by Eisele, Janssens and Raedschelders that tame blocks …

τ-tilting theory–an introduction

H Treffinger - arXiv preprint arXiv:2106.00426, 2020 - cambridge.org
The term τ-tilting theory was coined by Adachi, Iyama and Reiten in [1] at the beginning of
the 2010s. In their paper, the authors created a fresh approach to the study of two classical …
