Algebraic Knot Theory

Dror Bar-Natan – 16 October 2019

This will be a very "light" talk: I will explain why about 13 years ago, in order to have a say on some problems in knot theory, I've set out to find tangle invariants with some nice compositional properties. In other talks in Sydney, I have explained how such invariants were found - though they are yet to be explored and utilized.
