[HTML][HTML] Transfinite mutations in the completed infinity-gon

K Baur, S Gratz - Journal of Combinatorial Theory, Series A, 2018 - Elsevier
We introduce mutation along infinite admissible sequences for infinitely marked surfaces,
that is surfaces with infinitely many marked points on the boundary. We show that mutation …

[HTML][HTML] Unfolding of sign-skew-symmetric cluster algebras and its applications to positivity and F-polynomials

M Huang, F Li - Advances in Mathematics, 2018 - Elsevier
Using skew-symmetric matrices of infinite rank, the unfolding approach is extended from
skew-symmetrizable matrices to acyclic sign-skew-symmetric matrices. Applying this …

Cluster automorphism groups of cluster algebras with coefficients

W Chang, B Zhu - Science China Mathematics, 2016 - Springer
We study the cluster automorphism group of a skew-symmetric cluster algebra with
geometric coefficients. We introduce the notion of gluing free cluster algebra, and show that …

[HTML][HTML] On rooted cluster morphisms and cluster structures in 2-Calabi–Yau triangulated categories

W Chang, B Zhu - Journal of Algebra, 2016 - Elsevier
We study rooted cluster algebras and rooted cluster morphisms which were introduced in [1]
recently and cluster structures in 2-Calabi–Yau triangulated categories. An example of …

Based cluster algebras of infinite ranks

F Qin - arXiv preprint arXiv:2409.02881, 2024 - arxiv.org
We extend based cluster algebras from finite ranks to infinite ranks. By extending (quantum)
cluster algebras associated with double Bott-Samelson cells, we recover infinite rank cluster …

[HTML][HTML] Infinite rank surface cluster algebras

İ Çanakçı, A Felikson - Advances in Mathematics, 2019 - Elsevier
We generalise surface cluster algebras to the case of infinite surfaces where the surface
contains finitely many accumulation points of boundary marked points. To connect different …

[HTML][HTML] Graded quantum cluster algebras of infinite rank as colimits

JE Grabowski, S Gratz - Journal of Pure and Applied Algebra, 2018 - Elsevier
We provide a graded and quantum version of the category of rooted cluster algebras
introduced by Assem, Dupont and Schiffler and show that every graded quantum cluster …
