Triangulations of 3-manifolds with essential edges
Craig D. Hodgson, J. Hyam Rubinstein, Henry Segerman +1
We define essential and strongly essential triangulations of 3-manifolds, and give four constructions using different tools (Heegaard splittings, hierarchies of Haken 3-manifolds,…
Non-geometric veering triangulations
Craig D. Hodgson, Ahmad Issa, Henry Segerman
Recently, Ian Agol introduced a class of "veering" ideal triangulations for mapping tori of pseudo-Anosov homeomorphisms of surfaces punctured along the singular points. These tria…
Collection of abstracts of the Workshop on Triangulations in Geometry and Topology at CG Week 2014 in Kyoto
Jonathan Spreer, Uli Wagner, Benjamin A. Burton +3
This workshop about triangulations of manifolds in computational geometry and topology was held at the 2014 CG-Week in Kyoto, Japan. It focussed on computational and combinatorial…
The Quaternion Group as a Symmetry Group
Vi Hart, Henry Segerman
We briefly review the distinction between abstract groups and symmetry groups of objects, and discuss the question of which groups have appeared as the symmetry groups of physical…
