Torus Fibrations and Localization of Index III

Abstract

This paper is the third of the series concerning the localization of the index of Dirac-type operators. In our previous papers we gave a formulation of index of Dirac-type operators on open manifolds under some geometric setting, whose typical example was given by the structure of a torus fiber bundle on the ends of the open manifolds. We introduce two equivariant versions of the localization. As an application, we give a proof of Guillemin-Sternberg’s quantization conjecture in the case of torus action.
