Class A Spacetimes
Stefan Suhr
We introduce class A spacetimes, i.e. compact vicious spacetimes such that the Abelian cover is globally hyperbolic. We study the main properties of cla…

Closed Geodesics in Lorentzian Surfaces
Stefan Suhr
We show that every closed Lorentzian surface contains at least two closed geodesics. Explicit examples show the optimality of this claim. Refining this result we relate the least n…

Homologically maximizing geodesics in conformally flat tori
Stefan Suhr
We study homologically maximizing timelike geodesics in conformally flat tori. A causal geodesic in such a torus is said to be homologically maximizing if one (hence every) lif…
