Low-dimensional GKM theory
Oliver Goertsches, Panagiotis Konstantis, Leopold Zoller
GKM theory is a powerful tool in equivariant topology and geometry that can be used to generalize classical ideas from (quasi)toric manifolds to more general torus actions. After a…
Realization of GKM fibrations and new examples of Hamiltonian non-Kähler actions
Oliver Goertsches, Panagiotis Konstantis, Leopold Zoller
We classify fibrations of abstract -regular GKM graphs over -regular ones, and show that all fiberwise signed fibrations of this type are realized as the projectivization of…
A counting invariant for maps into spheres and for zero loci of sections of vector bundles
Panagiotis Konstantis
The set of unrestricted homotopy classes where is a closed and connected spin -manifold is called the -th cohomotopy group of . Moreover it is k…
GKM theory and Hamiltonian non-Kähler actions in dimension
Oliver Goertsches, Panagiotis Konstantis, Leopold Zoller
Using the classification of -dimensional manifolds by Wall, Jupp and Žubr, we observe that the diffeomorphism type of simply-connected, compact -dimensional integer GKM …
Vector bundles and cohomotopies of spin 5-manifolds
Panagiotis Konstantis
The purpose of this paper is two-fold: On the one side we would like to close a gap on the classification of vector bundles over -manifolds. Therefore it will be necessary to st…
Symplectic and Kähler structures on biquotients
Oliver Goertsches, Panagiotis Konstantis, Leopold Zoller
We construct symplectic structures on roughly half of all equal rank biquotients of the form , where is a compact simple Lie group and a torus, and investigate Hamilt…
