Mathematics Colloquium: A D'Ambra Theorem in conformal Lorentzian geometry

Speaker: Karin Melnick, University of Maryland

Title: A D'Ambra Theorem in conformal Lorentzian geometry

Abstract:
D'Ambra proved in 1988 that the isometry group of a compact, simply connected, real-analytic Lorentzian manifold must be compact. I will discuss my recent theorem that the conformal group of such a manifold must also be compact, and how it relates to the Lorentzian Lichnerowicz Conjecture.
