Discrete embeddings of hyperbolic groups with Pontryagin-surface boundaries
Jiming Ma, Junseo Yoon, Fangting Zheng
Let be the quotient of the closed disk obtained by identifying boundary points under rotation through angle . For every , we construct a hyperbolic right-…
Several families of incommensurable noncompact hyperbolic Coxeter polytopes
Lizi Guo, Jiming Ma, Yourong Zang +1
We classify all 141 finite-volume hyperbolic Coxeter five-dimensional polytopes with eight facets, of which 125 are noncompact. Using maximal-cusp density and a noncompact analog o…

Algebraic fibrations of certain hyperbolic 4-manifolds
Jiming Ma, Fangting Zheng
Algebraically fibering group is an algebraic generalization of the fibered 3-manifold group in higher dimensions. Let and be the cusped and compac…
