Higher-dimensional perfect fluids and empty singular boundaries
Ricardo E. Gamboa Saravi
In order to find out whether empty singular boundaries can arise in higher dimensional Gravity, we study the solution of Einstein's equations consisting in a ()-dimensional st…
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…
The Gravitational Field of a Plane Slab
Ricardo E. Gamboa Saravi
We discuss the exact solution of Einstein's equation corresponding to a static and plane symmetric distribution of matter with constant positive density located below matched…
Infinite slabs and other weird plane symmetric space-times with constant positive density
Ricardo E. Gamboa Saravi
We present the exact solution of Einstein's equation corresponding to a static and plane symmetric distribution of matter with constant positive density located below . This s…
Dirac Operator on a disk with global boundary conditions
H. Falomir, R. E. Gamboa Saraví, E. M. Santangelo
We compute the functional determinant for a Dirac operator in the presence of an Abelian gauge field on a bidimensional disk, under global boundary conditions of the type introduce…
The -function answer to parity violation in three dimensional gauge theories
R. E. Gamboa Saravi, G. L. Rossini, F. A. Schaposnik
We study parity violation in -dimensional gauge theories coupled to massive fermions. Using the -function regularization approach we evaluate the ground state fermion curre…
