Odd-dimensional GKM-manifolds of non-negative curvature

Christine Escher, Oliver Goertsches, Catherine Searle

We prove for closed, odd-dimensional GKM $_{3}$ manifolds of non-negative sectional curvature that both the equivariant and the ordinary rational cohomology split off the cohomology o…

On the topology of metric $f$ - $K$ -contact manifolds

Oliver Goertsches, Eugenia Loiudice

We observe that the class of metric $f$ - $K$ -contact manifolds, which naturally contains that of $K$ -contact manifolds, is closed under forming mapping tori of automorphisms of the…

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 $T^{2}$ …
