Verified computations for hyperbolic 3-manifolds
Neil Hoffman, Kazuhiro Ichihara, Masahide Kashiwagi +3
For a given cusped 3-manifold admitting an ideal triangulation, we describe a method to rigorously prove that either or a filling of admits a complete hyperbolic struct…
The big Dehn surgery graph and the link of S^3
Neil R. Hoffman, Genevieve S. Walsh
In a talk at the Cornell Topology Festival in 2005, W. Thurston discussed a graph which we call "The Big Dehn Surgery Graph", B. Here we explore this graph, particularly the link o…
Null-homologous exotic surfaces in 4-manifolds
Neil Hoffman, Nathan Sunukjian
In this paper we exhibit infinite families of embedded tori in 4-manifolds that are topologically isotopic but smoothly distinct. The interesting thing about these tori is that the…
On manifolds with multiple lens space filings
Kenneth L. Baker, Brandy Guntel Doleshal, Neil Hoffman
An irreducible 3--manifold with torus boundary either is a Seifert fibered space or admits at most three lens space fillings according to the Cyclic Surgery Theorem. We examine the…
