A closed formula for the evaluation of $\mathfrak{sl}_N$-foams (1702.04140v3)
Published 14 Feb 2017 in math.QA and math.GT
Abstract: We give a purely combinatorial formula for evaluating closed decorated foams. Our evaluation gives an integral polynomial and is directly connected to an integral equivariant version of the $\mathfrak{sl}_N$ link homology categorifying the $\mathfrak{sl}_N$ link polynomial. We also provide connections to the equivariant cohomology rings of partial flag manifolds.
