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 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...
2002Vol.37No.6pp.667-670DOI: Cosmological Constant and Stability of the Cosmological Models WANG Yong-Jiu and TANG Zhi-Ming Institute of Physics, Hunan Normal University...
2004Vol.41No.5pp.726-728DOI: Bianchi-Type II String Cosmological Models with Bulk Viscosity WANG Xing-Xiang Department of Physics, Anhui Normal University, Wuhu 241000, ...
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...
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 ...
