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 link homology categorifying the link polynomial. We also provide connections to the equivariant cohomology rings of partial flag manifolds.
