Convexity theorems for varieties invariant under a Borel subgroup
Victor Guillemin, Reyer Sjamaar
Atiyah proved that the moment map image of the closure of an orbit of a complex torus action is convex. Brion generalized this result to actions of a complex reductive group. We ex…
Assignments and Abstract Moment Maps
Viktor L. Ginzburg, Victor Guillemin, Yael Karshon
moment maps arise as a generalization of genuine moment maps on symplectic manifolds when the symplectic structure is discarded, but the relation between the mapping and the action…
The relation between compact and non-compact equivariant cobordisms
Viktor L. Ginzburg, Victor L. Guillemin, Yael Karshon
We show that the theory of stable complex -cobordisms, for a torus , is embedded into the theory of stable complex -cobordisms of not necessarily compact manifolds equippe…
Cobordism theory and localization formulas for Hamiltonian group actions
Viktor Ginzburg, Victor Guillemin, Yael Karshon
We announce the following result and give several applications: A Hamiltonian -space (for a torus) with isolated fixed points is cobordant to a disjoint union of weighted pr…
