**Title: **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 $sl_2$.
