Associahedra for finite‐type cluster algebras and minimal relations between g‐vectors

A Padrol, Y Palu, V Pilaud… - Proceedings of the …, 2023 - Wiley Online Library
We show that the mesh mutations are the minimal relations among the gg‐vectors with
respect to any initial seed in any finite‐type cluster algebra. We then use this algebraic result …

From the lattice of torsion classes to the posets of wide subcategories and ICE-closed subcategories

H Enomoto - Algebras and Representation Theory, 2023 - Springer
In this paper, we compute the posets of wide subcategories and ICE-closed subcategories
from the lattice of torsion classes in an abelian length category in a purely lattice-theoretical …

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 …

Pairwise compatibility for 2-simple minded collections

EJ Hanson, K Igusa - Journal of Pure and Applied Algebra, 2021 - Elsevier
In τ-tilting theory, it is often difficult to determine when a set of bricks forms a 2-simple
minded collection. The aim of this paper is to determine when a set of bricks is contained in …

Shard modules

W Dana, DE Speyer, H Thomas - arXiv preprint arXiv:2303.16332, 2023 - arxiv.org
Motivated by the goal of studying cluster algebras in infinite type, we study the stability
domains of modules for the preprojective algebra in the corresponding infinite types …
