Perfect fluid bianchi Type-I cosmological models with time varying G and Λ

Pramana, 2008
Bianchi Type-I cosmological models containing perfect fluid with time varying G and Λ have been presented. The solutions obtained represent an expansion scalar θ bearing a constant ratio to the anisotropy in the direction of space-like unit vector λ i .

Bianchi Type-III Cosmological Models with Gravitational Constant G and the Cosmological Constant Λ

Chinese Physics Letters, 2007
Einstein field equations with variable gravitational and cosmological constants are considered in the presence of perfect fluid for the Bianchi type-III universe by assuming conservation law for the energy-momentum tensor. Exact solutions of the field equations are obtained by using the scalar of expansion proportional to the shear scalar θ ∝ σ, which ...

Bianchi type-I cosmological models with time dependent G and Λ

Astrophysics and Space Science, 2008
Einstein field equations with variable gravitational and cosmological constants are considered in the presence of perfect fluid for Bianchi type-I universe by assuming the cosmological term proportional to the Hubble parameter. This variation law for vacuum density has recently been proposed by Schutzhold on the basis of quantum field estimations in ...

Bianchi type I two-fluid cosmological models with a variable G and Λ

Astrophysics and Space Science, 2008
This paper presents anisotropic, homogeneous two-fluid cosmological models in a Bianchi type I space–time with a variable gravitational constant G and cosmological constant Λ. In the two-fluid model, one fluid represents the matter content of the universe and another fluid is chosen to model the CMB radiation.

Füllung für Bureauxfenster : von Herrn G. Bianchi. Zch

1913
Bei "G. Bianchi" dürfte es sich wohl um den Mailänder Traiteur Giuseppe Bianchi handeln, der seit 1881 an der Zürcher Strehlgasse erfolgreich Gemüse, Obst und italienische Wurstwaren verkaufte, oder um dessen gleichnamigen Sohn, der ab 1920 das Geschäft an der Marktgasse ...

The general class of Bianchi cosmological models with dark energy and variable Λ and G in viscous cosmology

Pramana, 2017
The general class of Bianchi cosmological models with dark energy in the form of modified Chaplygin gas with variable Λ and G and bulk viscosity have been considered. We discuss three types of average scale factor by using a special law for deceleration parameter which is linear in time with negative slope.
