A Poly-Time Knot Polynomial Via Solvable Approximation
by
Dror Bar-Natan
University of Toronto

Rozansky (1996) and Overbay (2013) described a spectacular knot polynomial that failed to attract the attention it deserved as the first poly-time-computable knot polynomial since Alexander's (1928) and (in my opinion) as the second most likely knot polynomial (after Alexander's) to carry topological information. With Roland van der Veen, I will explain how to compute the Rozansky polynomial using some new commutator-calculus techniques and a Lie algebra g1 which is at the same time solvable and an approximation of the simple Lie algebra sl(2).
