L.R.S. Bianchi type II Stiff Fluid cosmological model with Decaying Vacuum Energy Density $\Lambda$ in general relativity
LRS Bianchi type II models Cosmological constant
2010/12/20
Locally rotationally symmetric (L.R.S.) Bianchi type II stiff fluid cos-mological model is investigated. To get the deterministic model of the universe, we have assumed a condition A = Bm between metr...
Effective Theory in Spinfoam Cosmology: A First Order LQG-corrected FRW Cosmology and the Stiff Fluid
Effective Theory Spinfoam Cosmology First Order LQG-corrected FRW Cosmology Stiff Fluid
2010/12/20
We present an effective theory of a basic holomorphic spinfoam cosmology peaked on homoge-
neous isotropic metrics. The quantum-corrected Hamiltonian constraint of this effective theory is motivated ...
Five Dimensional Stiff Fluid Models in Lyra Geometry
Five dimensional cosmological model stiff fluid Lyra geometry
2010/4/8
We have constructed stiff fluid cosmological models in five dimensional space-time based on Lyra geometry. Some physical and geometrical properties of the models are discussed.
