Title: Algorithms and complexity for Turaev-Viro invariants
Speaker: Jonathan Spreer, The University of Queensland, Australia
Date: 13 November 2015
Time: 4 pm
Venue: LH-1

The Turaev-Viro invariants are a powerful family of topological invariants for distinguishing between different 3-manifolds. They are invaluable for mathematical software, but current algorithms to compute them require exponential time. I will discuss this family of invariants, and present an explicit fixed-parameter tractable algorithm for arbitrary r which is practical—and indeed preferable—to the prior state of the art for real computation.
