Localization theorems by symplectic cuts

Lisa Jeffrey, Mikhail Kogan

Given a compact symplectic manifold M with the Hamiltonian action of a torus T, let zero be a regular value of the moment map, and M_0 the symplectic reduction at zero. Denote by κ…

Morse theory on Hamiltonian G-spaces and equivariant K-theory

Victor Guillemin, Mikhail Kogan

Let $G$ be a torus and $M$ a compact Hamiltonian $G$ -manifold with finite fixed point set $M^{G}$ . If $T$ is a circle subgroup of $G$ with $M^{G} = M^{T}$ , the $T$ -moment map is a Morse fu…
