»Closed geodesics on closed orbifolds«

Abstract:
Every closed Riemannian manifold has a closed geodesic. For closed Riemannian orbifolds this question is open in general. In the talk we explain what is known about this question. In particular, we show that on bad orbifolds and in odd dimensions closed geodesics always exist. Depending on the time we also discuss or announce new systolic inequalities for 2-orbifolds (even for S^2) and for contact 3-manifolds.

 

Hierzu ergeht herzliche Einladung.
