Convexity and Geodesics in Lorentzian Geometry

Bill Karr (University of Illinois at Urbana-Champaign)

Abstract: Lorentzian geometry is the mathematical foundation of general relativity. We will introduce the notion of a space-time, define geodesics and geodesic connectedness in this setting, and, time permitting, discuss my research on the relationship between convexity and geodesic connectedness.
