On moduli spaces of invariant psc-metrics on quasitoric manifolds.

Abstract: Quasitoric manifolds are certain nice even-dimensional manifolds with an action of an half-dimensional torus. In previous work it has been shown that each such manifold admits an invariant metric of positive scalar curvature. In this talk I will describe how to extend this construction to a constriction of families of psc-metrics. This yields non-trivial elements in the homotopy groups of moduli spaces of invariant metrics of positive scalar curvature on quasitoric manifolds.
