GIM and Elliptic Lie algebras via Ringel--Hall Lie algebras

Changjian Fu, Zhanhong Liang, Ming Lu

For any symmetrizable generalized intersection matrix (GIM) $C$ , we construct an acyclic valued quiver $(Q, d)$ endowed with an involution $θ$ . Let $D$ be the bou…

Are cluster automorphism groups finitely generated?

Changjian Fu, Zhanhong Liang, Yinzhi Wang

This paper investigates the finite generation of cluster automorphism groups. By applying the pseudo $N$ -grading introduced in our previous work, we establish a sufficient…

Pseudo grading on cluster automorphism group with application to cluster algebras of rank $3$

Changjian Fu, Zhanhong Liang

We introduce a pseudo $N$ -grading on the cluster auotmorphism group $Aut (A)$ with respect to an initial seed of $A$ , which consists of a…
