Regularity of a double null coordinate system for Kerr-Newman-de Sitter spacetimes
Anne T. Franzen, Pedro M. Girão
We construct a double null coordinate system for Kerr-Newman-de Sitter spacetimes and prove that the two-spheres given by the intersection of the hypersurfa…
Solutions of the wave equation bounded at the Big Bang
Pedro M. Girão, José Natário, Jorge Drumond Silva
By solving a singular initial value problem, we prove the existence of solutions of the wave equation which are bounded at the Big Bang in the Friedmann-Lemaitre-Robert…
