Higher Steenrod squares for Khovanov homology
Published 7 Feb 2019 in math.AT and math.GT | (1902.02839v3)
Abstract: We describe stable cup-i products on the cochain complex with $F2$ coefficients of any augmented semi-simplicial object in the Burnside category. An example of such an object is the Khovanov functor of Lawson, Lipshitz and Sarkar. Thus we obtain explicit formulas for cohomology operations on the Khovanov homology of any link.
