Algebraic vs geometric categorification of the Alexander polynomial : a spectral sequel (Emmanuel Wagner, Université de Paris)

01.06.2023 14:15

We construct a spectral sequence from the gl0-homology, an algebraic categorification of the Alexander polynomial to the knot Floer homology. This spectral sequence is of Bockstein type and comes from a subtle manipulation of coefficients. The main tools are quantum traces of foams and of singular Soergel bimodules.

This is a joint work with Anna Beliakova, Kris Putyra, and Louis-Hadrien Robert.
