Louis-Hadrien Robert: Categorification of 1 and of the Alexander polynomial (RLGTS, 11 November 2020)

Abstract:

I'll give a combinatorial and down-to-earth definition of the symmetric gl(1) homology. It is a (non-trivial) link homology which categorifies the trivial link invariant (equal to 1 on every link). Then I'll explain how to use this construction to obtain colored categorification of the Alexander polynomial. (joint with E. Wagner)
