A Poly-Time Knot Polynomial Via Solvable Approximation
Abstract:
I will construct the first poly-time-computable knot polynomial since Alexander's (1928) by using some new commutator-calculus techniques and a Lie algebra ${\mathfrak g}_1$ which is at the same time solvable and an approximation of the simple Lie algebra $sl_2$. Notes for the talk can be found at http://www.math.toronto.edu/drorbn/Talks/UNC-1610/
