On well-posedness of the Cauchy problem for the wave equation in static spherically symmetric spacetimes
Ricardo E. Gamboa Saraví, Marcela Sanmartino, Philippe Tchamitchian
We give simple conditions implying the well-posedness of the Cauchy problem for the propagation of classical scalar fields in general (n+2)-dimensional static and spherically symme…
An alternative well-posedness property and static spacetimes with naked singularities
Ricardo E. Gamboa Saravi, Marcela Sanmartino, Philippe Tchamitchian
In the first part of this paper, we show that the Cauchy problem for wave propagation in some static spacetimes presenting a singular time-like boundary is well posed, if we only d…
Divergence operator and Poincare inequalities on arbitrary bounded domains
Ricardo Duran, Maria-Amelia Muschietti, Emmanuel Russ +1
Let be an arbitrary bounded domain of . We study the right invertibility of the divergence on in weighted Lebesgue and Sobolev spaces on , and rely this invertibil…
