Junior Topology: SnapPea and the Epstein-Penner Decomposition by Casandra Monroe in Zoom
SnapPea is a computational tool developed in the early 90s due to Weeks, and further expanded upon by Dunfield and Culler. It's been incredibly useful in the study of hyperbolic 3-manifolds--you can ask the software to give figures of cusp neighborhoods, compute invariants such as the hyperbolic volume, or even just ask if two manifolds are isometric. In this talk, we will go over the Epstein-Penner Decomposition of a manifold and discuss how SnapPea uses it to perform some of the computations we care about. There may also be pictures, time permitting! Submitted by
