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…
On the existence of bounded solutions for a nonlinear elliptic system
Ricardo G. Duran, Marcela Sanmartino, Marisa Toschi
This work deals with the system , with Dirichlet boundary condition in a domain $Ω\subset\RR^n$, where is a ball if or a smooth…
About radial Toeplitz operators on Segal-Bargmann and spaces
Romina A. Ramírez, Gerardo L. Rossini, Marcela Sanmartino
We discuss Toeplitz operators on the Segal-Bargmann space as functional realizations of anti-Wick operators on the Fock space. In the special case of radial symbols we exploit the…
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…
About composition of Toeplitz operators in Segal-Bargmann Space
Romina Ramirez, Marcela Sanmartino
Some positive results about the composition of Toeplitz operators on the Segal-Bargmann space are presented. A Wick symbol where it is not possible to construct its associated Toep…
