Duistermaat-Heckman formula for a torus action on a generalized Calabi-Yau manifold and localization formula
Yasufumi Nitta
Abstract
This note is an addendum to our earlier work humi. In humi, we studied a Hamiltonian action for a generalized Calabi-Yau manifold and showed that the Duistermaat-Heckman theorem holds. The purpose of this note is to show that the density function of the Duistermaa-Heckman measure is a piecewise polynomial. We also prove that the localization formula holds.
