Projective deformations of weakly orderable hyperbolic Coxeter orbifolds
Suhyoung Choi, Gye-Seon Lee
A Coxeter -orbifold is an -dimensional orbifold based on a polytope with silvered boundary facets. Each pair of adjacent facets meet on a ridge of some order , whose neigh…

The definability criterions for convex projective polyhedral reflection groups
Kanghyun Choi, Suhyoung Choi
Following Vinberg, we find the criterions for a subgroup generated by reflections $Γ\subset \SL^{\pm}(n+1,\mathbb{R})$ and its finite-index subgroups to be definable over $\mathbb{…

Topological tameness of Margulis spacetimes
Suhyoung Choi, William Goldman
We show that Margulis spacetimes without parabolic holonomy are topologically tame. A Margulis spacetime is the quotient of the -dimensional Minkowski space by a free proper iso…
