Presentations of mapping class groups and an application to cluster algebras from surfaces
Jinlei Dong, Fang Li
In this paper, we give presentations of the mapping class groups of marked surfaces stabilizing boundaries for any genus. Note that in the existing works, the mapping class groups…

On the first Hochschild cohomology of admissible algebras
Fang Li, Dezhan Tan
Our aim in this paper is to investigate the first Hochschild cohomology of {\em admissible algebras} which can be seen as a generalization of basic algebras. For this purpose, we s…
