Title: Null Distance on a Spacetime

Abstract: In contrast to the Riemannian setting, a Lorentzian manifold
(M,g) is not known to possess any naturally induced distance function. I
will first try to explain why that is, starting with some of the basics of
spacetime (Lorentzian) geometry. We will then discuss a `null distance
function' introduced in joint work with Christina Sormani, some of its
properties, examples, and some open questions.
