Renormalization and Geometry in the Grosse-Wulkenhaar Model

Alexander Hock (Oxford University)

The Grosse-Wulkenhaar model (GW) is a euclidean scalar quantum field theory with quartic interaction on a non-commutative space, more precisely on the Moyal space. The most interesting property of...

Global hyperbolicity in general relativity and in less regular theories

Ettore Minguzzi (Florence)

I discuss the properties of global hyperbolicity in general relativity and how its definition should be modified under low regularity assumptions.

Local and global scalar curvature rigidity of Einstein manifolds

Klaus Kröncke

An Einstein manifold is called scalar curvature rigid if there are no compactly supported volume-preserving deformation of the metric which increase the scalar curvature. We give various...
