John Beem will continue his research in Lorentzian geometry.               This is an area of differential geometry which provides the                     mathematical foundations of relativity. It involves the study of                indefinite or Lorentzian metrics in place of the more usual                     Riemannian metrics.                                                                  Beem will study conditions which imply the stability of                    geodesic incompleteness. This has already been studied in the                   context of certain big bang models. He will also investigate the                influence of pseudoconvexity on geodesic systems. Pseudoconvexity               arises in the global solvability of pseudodifferential equations                and is useful in geometry as an internal form of completeness.
