On minimal ideal triangulations of cusped hyperbolic 3-manifolds
William Jaco, Hyam Rubinstein, Jonathan Spreer +1
Previous work of the authors studies minimal triangulations of closed 3-manifolds using a characterisation of low degree edges, embedded layered solid torus subcomplexes and 1-dime…

The 3D-index and normal surfaces
Stavros Garoufalidis, Craig Hodgson, Neil Hoffman +1
Dimofte, Gaiotto and Gukov introduced a powerful invariant, the 3D-index, associated to a suitable ideal triangulation of a 3-manifold with torus boundary components. The 3D-index…

Four-dimensional Haken cobordism theory
Bell Foozwell, Hyam Rubinstein
Cobordism of Haken -manifolds is defined by a Haken -manifold whose boundary has two components, each of which is a closed Haken -manifold. In addition, the inclus…
