Modified-gravity wormholes without exotic matter
Tiberiu Harko, Francisco S. N. Lobo, M. K. Mak +1
A fundamental ingredient in wormhole physics is the flaring-out condition at the throat which, in classical general relativity, entails the violation of the null energy condition.…
Viscous dissipative Chaplygin gas dominated homogenous and isotropic cosmological models
C. S. J. Pun, L. Á. Gergely, M. K. Mak +3
The generalized Chaplygin gas, which interpolates between a high density relativistic era and a non-relativistic matter phase, is a popular dark energy candidate. We consider a gen…
Chaplygin gas dominated anisotropic brane world cosmological models
M. K. Mak, T. Harko
We present exact solutions of the gravitational field equations in the generalized Randall-Sundrum model for an anisotropic brane with Bianchi type I geometry, with a generalized C…
Relativistic Compact Objects in Isotropic Coordinates
M. K. Mak, T. Harko
We present a matrix method for obtaining new classes of exact solutions for Einstein's equations representing static perfect fluid spheres. By means of a matrix transformation, we…
Conformally symmetric vacuum solutions of the gravitational field equations in the brane-world models
T. Harko, M. K. Mak
A class of exact solutions of the gravitational field equations in the vacuum on the brane are obtained by assuming the existence of a conformal Killing vector field, with non-stat…
Anisotropy in Bianchi-type brane cosmologies
T. Harko, M. K. Mak
The behavior near the initial singular state of the anisotropy parameter of the arbitrary type, homogeneous and anisotropic Bianchi models is considered in the framework of the bra…
