Browsing the universe
The talk explores Miguel Sanchez's contributions to the long-standing open question of the existence of Cauchy temporal functions and metric splittings on globally hyperbolic spacetimes, beginning with the ground-breaking joint result with Antonio Bernal answering this question, which allows for slicing the book of the universe into pages of equal time. The talk gives an overview of the history of this question and the answer as well as later refinements, ramifications and consequences, e.g. for symmetric-hyperbolic equations, steep temporal functions, closed isometric embeddings, conformal embeddings, and functors joining Lorentzian and Riemannian categories.
