Twist automorphisms and Poisson structures
We introduce (quantum) twist automorphisms for upper cluster algebras and cluster Poisson
algebras with coefficients. Our constructions generalize the twist automorphisms for …

[HTML][HTML] Quasi-homomorphisms of quantum cluster algebras
In this paper, we study quasi-homomorphisms of quantum cluster algebras, which are
quantum analogy of quasi-homomorphisms of cluster algebras introduced by Fraser. For a …

A note on cluster automorphism groups
W Chang, R Schiffler - arxiv preprint arxiv:1812.05034, 2018 - arxiv.org
We conjecture a characterization of a cluster automorphism as an algebra homomorphism
from the cluster algebra to itself that restricts to a bijection between two clusters. This …
