Terminal Geometry of Rank-Two Nielsen Reduction on Simplicial Trees

Yukun Du, Sa'ar Hersonsky

Let $X$ be a locally finite simplicial tree, and let $Γ = ⟨ γ_{1}, γ_{2} ⟩ \leq Aut (X)$ be a discrete subgroup generated by hyperbolic automorphisms acting without invers…

Busemann-Selberg Functions and Completeness for Dirichlet-Selberg domains in $S L (n, R) / S O (n, R)$

Yukun Du

We establish a general completeness criterion for Dirichlet-Selberg domains in the symmetric space $S L (n, R) / S O (n)$ . By introducing and analyzing Busemann-Selberg functions…
