A quantum categorification of the Alexander polynomial
Published 15 Feb 2019 in math.GT and math.QA | (1902.05648v3)
Abstract: 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.
