A quantum categorification of the Alexander polynomial

Louis-Hadrien Robert, Emmanuel Wagner

Published 2019-02-15Version 1

Using a modified foam evaluation, we give a categorification of the Alexander polynomial of a knot. We also give a purely algebraic version of this knot homology which makes it appear as the infinite page of a spectral sequence starting at the reduced triply graded link homology of Khovanov--Rozansky.

Comments: 50 pages, many figures. Comments welcome!
