Viscous cosmologies in scalar-tensor theories for Kasner type metrics
M. Cataldo, S. del Campo, P. Salgado
In a viscous Bianchi type I metric of the Kasner form, it is well known that it is not possible to describe an anisotropic physical model of the universe, which satisfies the secon…
(2+1)-Dimensional Black Hole with Coulomb-like Field
M. Cataldo, N. Cruz, S. del Campo +1
A (2+1)-static black hole solution with a nonlinear electric field is derived. The source to the Einstein equations is a nonlinear electrodynamics, satisfying the weak energy condi…
Scalar fields in an anisotropic closed universe
Mauricio Cataldo, Sergio del Campo
We study in this article a class of homogeneous, but anisotropic cosmological models in which shear viscosity is included. Within the matter content we consider a component (the qu…
Regular (2+1)-dimensional black holes within non-linear Electrodynamics
Mauricio Cataldo, Alberto Garcia
(2+1)-regular static black hole solutions with a nonlinear electric field are derived. The source to the Einstein equations is an energy momentum tensor of nonlinear electrodynamic…
Comment on "Viscous cosmology in the Kasner metric"
M. Cataldo, S. del Campo
We show in this comment that in an anisotropic Bianchi type I model of the Kasner form, it is not possible to describe the growth of entropy, if we want to keep the thermodynamics…
BTZ black hole from (3+1) gravity
M. Cataldo, S. del Campo, A. Garcia
We propose an approach for constructing spatial slices of (3+1) spacetimes with cosmological constant but without a matter content, which yields (2+1) vacuum with solutions. Th…
