Finiteness and boundedness of positive monotone Hamiltonian GKM $_{3}$ spaces

Panagiotis Konstantis, Silvia Sabatini, Leopold Zoller

In this paper, we establish three finiteness and boundedness theorems for compact positive monotone symplectic manifolds endowed with special actions, called GKM $_{3}$ , which general…

Realization of GKM fibrations and new examples of Hamiltonian non-Kähler actions

Oliver Goertsches, Panagiotis Konstantis, Leopold Zoller

We classify fibrations of abstract $3$ -regular GKM graphs over $2$ -regular ones, and show that all fiberwise signed fibrations of this type are realized as the projectivization of…

GKM theory and Hamiltonian non-Kähler actions in dimension $6$

Oliver Goertsches, Panagiotis Konstantis, Leopold Zoller

Using the classification of $6$ -dimensional manifolds by Wall, Jupp and Žubr, we observe that the diffeomorphism type of simply-connected, compact $6$ -dimensional integer GKM $T^{2}$ …

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 $G // T$ , where $G$ is a compact simple Lie group and $T$ a torus, and investigate Hamilt…
