Bianchi V Brane-world Cosmology with a Generalized Chaplygin Gas
Özgür Sevinc, Gülçin, Uluyazi
In the context of brane cosmology, we investigate exact solution of the gravitational field equations in the Randall-Sundrum model for an anisotropic brane with Bianchi V geometry,…

Bianchi Models with Chaplygin Gas
Gülçin, Uluyazi, Özgür Sevinc
Einstein Gravitational Field Equations (EFE) of Chaplygin gas dominated Bianchi-type models are obtained by using metric approximation. The solutions of equations for a special cas…
