GKM manifolds with low Betti numbers
A GKM manifold is a symplectic manifold with a torus action such that the fixed points are isolated and the isotropy weights at the fixed points are linearly independent. Each GKM manifold has a GKM graph which contains much of the topological information of the manifold, in particular the …

The topology of GKM spaces and GKM fibrations
… computation of the equivariant cohomology of a GKM space. In particular we investigate the role that equivariant maps play in the computation of these cohomology rings. In the first part of the thesis, we describe some implications of the existence of an equivariant map p between an …
