Let $M = M0 × S1$ be a compact Lorentzian manifold of splitting type, equipped with a splitting metric. Provided that the fundamental group of $M0$ is finite, a result by Candela, Giannoni and Masiello ensures the existence of infinitely many closed timelike geodesics. I will present a quick view on their proof and discuss the case of an infinite fundamental group using some results by Galloway.
