Theory of Infinite Maximal Green Sequences: Finest Stability Data, CBHO Sequence and Cluster quiver pattern
Fang Li, Kangping Qu
In this paper, we introduce maximal green sequences of infinite length in abelian length categories and establish natural bijections among infinite maximal green sequences, finest…

The approach of cluster symmetry to Diophantine equations
Leizhen Bao, Fang Li
This paper aims to employ a cluster-theoretic approach to provide a class of Diophantine equations whose solutions can be obtained by starting from initial solutions through mutati…

Finest positroid subdivisions from maximal weakly separated collections
Gleb A. Koshevoy, Fang Li, Lujun Zhang
We adopt a formal and algebraic approach of Early \cite{E2} to study the positive tropical Grassmannian . Specifically, we deal with positroid subdi…
