In this paper, we localize the theory on a squashed S3 with SU(2) × U(1) isometry and a class of complex background. We see that certain kinds of shifts of the background gauge fields are crucial in obtaining nontrivial results, and the previously found results on this manifold can be incorporated in our results as special limits.
