Atypical generic directions in Teichmüller space
Matthew Gentry Durham, Chenxi Wu, Kejia Zhu
Motivated by geometrically capturing generic directions in Teichmüller space -- that is, tracking rays for random walks of the mapping class group -- we use work of Chaika--Masur--…
Zeta function and entropy for non-archimedean subhyperbolic dynamics
Liang-Chung Hsia, Hongming Nie, Chenxi Wu
Let be a complete non-archimedean field of characteristic equipped with a discrete valuation. We establish the rationality of the Artin-Mazur zeta function on the Julia set…
A lower bound on end-periodic stretch factors
Marissa Loving, Chenxi Wu
Given an end-periodic homeomorphism we give a lower bound on the Handel--Miller stretch factor of in terms of the core characteristic of , which is a measure of…
Principal minors of tree distance matrices
Harry Richman, Farbod Shokrieh, Chenxi Wu
We prove that the principal minors of the distance matrix of a tree satisfy a combinatorial expression involving counts of rooted spanning forests of the underlying tree. This gene…
