Four Parametric Regular Black Hole Solution
Eloy Ayón-Beato, Alberto García
We present a regular class of exact black hole solutions of Einstein equations coupled with a nonlinear electrodynamics source. For weak fields the nonlinear electrodynamics become…
Circular stationary cyclic symmetric spacetimes; conformal flatness
Alberto A. Garcia, Cuauhtemoc Campuzano
A subclassification of stationary spacetimes, endowed with one timelike and one spacelike Killing vectors, i.e., Petrov on spaces, is proposed. Special attention des…
Relationship between (2+1) and 3+1)--Friedmann--Robertson--Walker cosmologies
A. Garcia, M. Cataldo, S. del Campo
In this work we establish the correspondence between solutions to the Friedmann--Robertson--Walker cosmologies for perfect fluid and scalar field sources, where both ones fulfill s…
The Cotton tensor in Riemannian spacetimes
A. Garcia, F. W. Hehl, C. Heinicke +1
Recently, the study of three-dimensional spaces is becoming of great interest. In these dimensions the Cotton tensor is prominent as the substitute for the Weyl tensor. It is confo…
Exact vacuum solution of a (1+2)-dimensional Poincare gauge theory: BTZ solution with torsion
Alberto A. Garcia, Friedrich W. Hehl, Christian Heinicke +1
In (1+2)-dimensional Poincaré gauge gravity, we start from a Lagrangian depending on torsion and curvature which includes additionally {\em translational} and {\em Lorentzian} Cher…
All Static Circularly Symmetric Perfect Fluid Solutions of 2+1 Gravity
Alberto A. Garcia, Cuauhtemoc Campuzano
Via a straightforward integration of the Einstein equations with cosmological constant, all static circularly symmetric perfect fluid 2+1 solutions are derived. The structural func…
