Space-time convex functions and sectional curvature
Stephanie B. Alexander, William A. Karr
We show that in Lorentzian manifolds, sectional curvature bounds of the form , as defined by Andersson and Howard, are closely tied to space-time convex and …

Convex Functions and Geodesic Connectedness of Space-times
Stephanie B. Alexander, William A. Karr
This paper explores the relation between convex functions and the geometry of space-times and semi-Riemannian manifolds (an investigation initiated by Gibbons-Ishibashi). Specifica…
