Lecture by Benjamin Burton (University of Queensland, Australia): From parameterised to non-parameterised algorithms in knot theory

Jul 02, 2018 | 02:15 PM

We describe some recent developments in treewidth-based algorithms for knots, which exploit the structure of the underlying 4-valent planar graph. In particular, we show how these led to the first general sub-exponential-time algorithm for the HOMFLY-PT polynomial, and we describe some recent progress on parameterised algorithms for unknot recognition.
