On geodesics in low regularity
Clemens Sämann, Roland Steinbauer
We consider geodesics in both Riemannian and Lorentzian manifolds with metrics of low regularity. We discuss existence of extremal curves for continuous metrics and present several…

Geodesics in nonexpanding impulsive gravitational waves with , II
Clemens Sämann, Roland Steinbauer
We investigate all geodesics in the entire class of nonexpanding impulsive gravitational waves propagating in an (anti-)de Sitter universe using the distributional metric. We exten…
