Relative train tracks and generalized endperiodic graph maps
Yan Mary He, Chenxi Wu
Motivated by the work of Cantwell-Conlon-Fenley on endperiodic homeomorphisms of infinite type surfaces, we define and study endperiodic and generalized endperiodic maps of an infi…

Basmajian's identity over non-Archimedean local fields
Yan Mary He, Chenxi Wu
Let be a connected compact oriented surface with boundary and negative Euler characteristic. Let be a non-Archimedean local field. In this paper, we prove Basmajian's iden…
