Query: On F-term contribution to effective action   We apply equivariant integration technique, developed in the context of
instanton counting, to two dimensional N=2 supersymmetric Yang-Mills models.
Twisted superpotential for U(N) model is computed. Connections to the four
dimensional case are discussed. Also we make some comments about the eight
dimensional model which manifests similar features.
