In mathematics, the Duistermaat–Heckman formula, due to Duistermaat and Heckman (1982), states that the pushforward of the canonical (Liouville) measure...

well known for his article with his PhD student Gert Heckman [de] on the Duistermaat–Heckman formula, which will later be placed in the more general framework...

generalization to infinite-dimensional loop groups. Duistermaat and Heckman found a striking formula, saying that the push-forward of the Liouville measure...

as an extension of the Berline–Vergne– Atiyah– Bott formula (or the Duistermaat–Heckman formula) for equivariant integration to path integrals of certain...

non-equivariant cohomology. One important consequence of the formula is the Duistermaat–Heckman theorem, which states: supposing there is a Hamiltonian circle...
