Compact Lorentz manifolds with local symmetry

Karin Melnick

We prove a structure theorem for compact aspherical Lorentz manifolds with abundant local symmetry. If M is a compact, aspherical, real-analytic, complete Lorentz manifold such tha…

Actions of noncompact semisimple groups on Lorentz manifolds

Mohamed Deffaf, Karin Melnick, Abdelghani Zeghib

The above title is the same, but with "semisimple" instead of "simple," as that of a notice by N. Kowalsky. There, she announced many theorems on the subject of actions of simple L…
