In mathematics, the Duistermaat–Heckman formula, due to Шаблон:Harvs, states that the pushforward of the canonical (Liouville) measure on a symplectic manifold under the moment map is a piecewise polynomial measure. Equivalently, the Fourier transform of the canonical measure is given exactly by the stationary phase approximation.

Шаблон:Harvtxt and, independently, Шаблон:Harvtxt showed how to deduce the Duistermaat–Heckman formula from a localization theorem for equivariant cohomology.
