Properties of the Null Distance on a Spacetime

Explore the concept of null distance in spacetime geometry through this 33-minute conference talk from the Workshop on "Non-regular Spacetime Geometry" at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the metric space structure defined by the null distance, as introduced by Sormani and Vega. Examine various examples and investigate the relationship between metric space and spacetime structures. Gain insights into this advanced topic in mathematical physics and expand your understanding of non-regular spacetime geometry.
