DESCRIPTION:In 1998\, Goresky\, Kottwitz\, MacPherson introduced a class of $(S^1)^k$-actions on  smooth manifolds  with degenerate odd-dimensional cohomologies. They calculated the corresponding ring of equivariant cohomologies in terms of so-called GKM-graphs. Roughly speaking\, a GKM-graph of type $(n\,k)$ is an $n$-valent graph with labels from the lattice $\Z^k$ on its edges.
