# A Poly-Time Knot Polynomial Via Solvable Approximation

### Geometric Representation Theory Seminar, Toronto, September 22 2016

**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 $sl_2$.
