On topology changes in quantum field theory and quantum gravity
Benjamin Schulz
Two singularity theorems can be proven if one attempts to let a Lorentzian cobordism interpolate between two topologically distinct manifolds. On the other hand, Cartier and DeWitt…

Surfaces of section for geodesic flows of closed surfaces
Gonzalo Contreras, Gerhard Knieper, Marco Mazzucchelli +1
We prove several results concerning the existence of surfaces of section for the geodesic flows of closed orientable Riemannian surfaces. The surfaces of section that we constr…

Geodesic Anosov flows, hyperbolic closed geodesics and stable ergodicity
Gerhard Knieper, Benjamin H. Schulz
In this paper we show that the geodesic flow of a Finsler metric is Anosov if and only if there exists a open neighborhood of Finsler metrics all of whose closed geodesics ar…
