The signature of cusped hyperbolic 4-manifolds
Alexander Kolpakov, Stefano Riolo, Steven T. Tschantz
In this note we show that every integer is the signature of a non-compact, oriented, hyperbolic 4-manifold of finite volume, and give some partial results on the geography of such…
Hyperbolic 24-cell 4-manifolds with one cusp
John G. Ratcliffe, Steven T. Tschantz
In this paper, we describe all the hyperbolic 24-cell 4-manifolds with exactly one cusp. There are four of these manifolds up to isometry. These manifolds are the first examples of…
Co-Seifert fibrations of compact flat 3-orbifolds
John G. Ratcliffe, Steven T. Tschantz
This paper is a continuation of our previous paper, Co-Seifert fibrations of compact flat orbifolds, in which we developed the theory for classifying geometric fibrations of compac…
