Nekrasov's deformed partition functions of N=2 SUSY Yang-Mills theories are given by the integrations in the equivariant cohomology/Grothendieck groups of instanton moduli spaces over R4, which are quiver varieties associated with the Jordan quiver. They are analog of Donaldson invariants, and equal to Gromov-Witten invariants of certain noncompact Calabi-Yau 3-folds. We review recent results on them.
