Morse theory on Hamiltonian G-spaces and equivariant K-theory
Victor Guillemin, Mikhail Kogan
Let be a torus and a compact Hamiltonian -manifold with finite fixed point set . If is a circle subgroup of with , the -moment map is a Morse fu…
GKM theory for torus actions with non-isolated fixed points
Victor Guillemin, Tara S. Holm
Let be a compact symplectic manifold and a compact -dimensional torus. A Hamiltonian action, , of on is a GKM action if, for every , the isotr…
Potential functions and actions of tori on Kaehler manifolds
D. Burns, V. Guillemin
Let M be a Kaehler manifold with a free, holomorphic and Hamiltonian action of the standard n-torus T. We give a simple, explicit and canonical formula for the Kaehler potential on…
A GKM description of the equivariant cohomology ring of a homogeneous space
Victor Guillemin, Tara Holm, Catalin Zara
Let be a torus of dimension and a compact manifold. is a GKM manifold if the set of zero dimensional orbits in the orbit space is zero dimensional and t…
The mod 2 cohomology of fixed point sets of anti-symplectic involutions
Daniel Biss, Victor W. Guillemin, Tara S. Holm
Let be a compact, connected symplectic manifold with a Hamiltonian action of a compact -dimensional torus . Suppose that is an anti-symplectic involution compatib…
Symplectic implosion
Victor Guillemin, Lisa Jeffrey, Reyer Sjamaar
Let be a compact Lie group. We introduce the process of symplectic implosion, which associates to every Hamiltonian -manifold a stratified space called the imploded cross-se…
