Arithmeticity and geometrical commensurators
Yanlong Hao
We establish a coarse-geometric analogue of Margulis's commensurator criterion for groups acting on good Gromov-hyperbolic spaces. For a non-elementary -lattice ,…

On trace set of hyperbolic surfaces and a conjecture of Sarnak and Schmutz
Yanlong Hao
In this paper, we investigate the trace set of a Fuchsian lattice. There are two results of this paper: the first is that for a non-uniform lattice, we prove Scmutz's conjecture: t…
