Oscillations toward the singularity of LRS Bianchi type IX cosmological models with Vlasov matter
Oscillations singularity of LRS Bianchi type IX cosmological models Vlasov matter
2010/12/20
We analyze the dynamics of a class of cosmological solutions of the Einstein-Vlasov equa-
tions. These equations describe an ensemble of collisionless particles (which represent galaxies or clusters ...
Cosmological Models with Fractional Derivatives and Fractional Action Functional
Fractional Derivative and Integral Cosmology
2010/12/20
Cosmological models of a scalar field with dynamical equations containing fractional derivatives or derived from the Einstein-Hilbert action of fractional order, are constructed. A number of exact sol...

Five Dimensional Anisotropic Homogeneous Cosmological Models in Second Self Creation Theory of Gravitation
Five dimensions self creation theory anisotropic spacetime
2010/4/9
Five dimensional homogeneous anisotropic cosmological models in Barber's second self creation theory are constructed when the gravitational field is generated by a perfect fluid. Under the power law d...

Closed Isotropic Cosmological Steep Scalar Field Potential
2010/4/15
The dynamics of closed scalar field FRW cosmological models is studied for several types of exponentially and more than exponentially steep potentials. The parameters of scalar field potentials which ...
