über das Thema:

»Cohomogeneity One Alexandrov Spaces with Positive Curvature«

Alexandrov spaces are a synthetic generalization of Rie- mannian manifolds with a lower curvature bound. It is then a natural question that to what extent one can generalize the basic results of the Riemannian manifolds with a lower curvature bound to Alexandrov spaces. In this talk, I will explore this question in the context of co- homogeneity one actions on positively curved Alexandrov spaces. I will explain some obstructions to the existence of an invariant metric of pos- itive curvature on a cohomogeneity one Alexandrov space, and then I will give a classification of closed simply-connected cohomogeneity one Alexandrov spaces with positive curvature in dimensions at most 6. It is an ongoing project with F. Galaz-García.


Hierzu ergeht herzliche Einladung.
