Jeffrey and Kirwan gave expressions for intersection pairings on the reduced space of a Hamiltonian space in terms of iterated residues. Alekseev, Malkin, and Meinrenken introduced the notion of quasi-Hamiltonian spaces for which the moment map takes values in the group itself rather than in the dual of the Lie algebra, and developed the theory of quasi-Hamiltonian spaces. The theory includes counterparts of Hamiltonian reductions. Alekseev, Meinrenken, and Woodward proved a localization formula for group valued equivariant de Rham cohomology of a compact G-manifold. From this result a Duistermaat-Heckman formula for group valued moment maps was derived.In this paper, we construct the Hamiltonian space corresponding to a given quasi-Hamiltonian space. We use an important property of the Hamiltonian spaces: periodicity. We first prove a residue formula for intersection numbers in the reduced space of a quasi-Hamiltonian T-space (where T is a compact torus) by induction on r, the rank of T. From that result, we prove a residue formula for intersection pairings of the reduced spaces of a quasi-Hamiltonian G-space (where G is a compact Lie group). We show that the result agrees with that in Alekseev-Meinrenken-Woodward. We rely heavily on the method of Jeffrey and Kirwan (Intersection theory on moduli spaces, which is the reduced space of the quasi-Hamiltonian SU(n)-space SU(n)2g). For the more general class of compact Lie group, we make use of the result on diagonal bases given by Szenes and Brion-Vergne.

Thesis title: Volume Formula and Intersection Pairings of N-fold Reduced Products Let $ G $ be a semisimple compact connected Lie group. An $ N $-fold reduced product of $ G $ is the symplectic quotient of the Hamiltonian system of the Cartesian product of $ N $ coadjoint orbits of $ G $ under diagonal coadjoint action of $ G $ Quasi-Hamiltonian spaces, introduced by Alekseev, Malkin, and Meinrenken, are similar to Hamiltonian G-manifolds but with two significant differences: first, the 2-form on the manifold is neither closed nor nondegenerate, but one has control over the image of the differential of the 2-form, as well as the degeneracy locus of the 2-form, and The collection of mean values in the Mean value theorem. reference-request real-analysis measure-theory mean-value-theorem. modified 12 mins ago OOESCoupling 1, Regularity of conformal maps. ential-geometry is-of-pdes x-variables riemannian-geometry conformal-geometry. modified 29 mins ago seub 1, Here, is the equivariant Cartan 3-form determined by an invariant inner product on the Lie algebra .The condition that ω be nondegenerate is replaced by the weaker condition that everywhere.

It is a widely accepted view (appearing e.g. in excellent, standard textbooks on general relativity, too) that the canonical energy-momentum and spin tensors are well-defined and have relevance only in flat spacetime, and hence usually are underestimated and abandoned.
