Leistner, T.Munn, T.2024-09-122024-09-122023Comptes Rendus Mathematique (Academie des Sciences), 2023; 361(1):819-8240764-44420764-4442https://hdl.handle.net/2440/142293We show that a compact Lorentzian locally symmetric space is geodesically complete if the Lorentzian factor in the local de Rham–Wu decomposition is of Cahen–Wallach type or if the maximal flat factor is one-dimensional and time-like. Our proof uses a recent result by Mehidi and Zeghib and an earlier result by Romero and Sánchez.enThe authors retain unrestricted copyrights and publishing rights.
