Geodesic Deviation Equation in f(R) Gravity
Alejandro Guarnizo, Leonardo Castaneda, Juan M. Tejeiro
In this paper we study the Geodesic Deviation Equation (GDE) in metric f(R) gravity. We start giving a brief introduction of the GDE in General Relativity in the case of the standa…
Three Dimensional Charged Black Hole Inspired by Noncommutative Geometry
Alexis Larranaga, Juan Manuel Tejeiro
We find a new charged black hole in three-dimensional anti-de Sitter space using an anisotropic perfect fluid inspired by the noncommutative black hole as the source of matter and…
Noncommutative Geometry Inspired Rotating Black Hole in Three Dimensions
Juan Manuel Tejeiro, Alexis Larranaga
We find a new rotating black hole in three-dimensional anti-de Sitter space using an anisotropic perfect fluid inspired by the noncommutative black hole. We deduce the thermodynami…
Shear Dynamics in Bianchi I Cosmology
Diego Caceres, Leonardo Castaneda, Juan M. Tejeiro
We present the exact equation for evolution of Bianchi I cosmological model, considering a non-tilted perfect fluid in a matter dominated universe. We use the definition of shear t…
Boundary Term in Metric f(R) Gravity: Field Equations in the Metric Formalism
Alejandro Guarnizo, Leonardo Castaneda, Juan M. Tejeiro
The main goal of this paper is to get in a straightforward form the field equations in metric f(R) gravity, using elementary variational principles and adding a boundary term in th…
