Late Time Acceleration of the 3-Space in a Higher Dimensional Steady State Universe in Dilaton Gravity
Ozgur Akarsu, Tekin Dereli
We present cosmological solutions for (1+3+n)-dimensional steady state universe in dilaton gravity with an arbitrary dilaton coupling constant w and exponential dilaton self-intera…
The Dynamical Evolution of 3-Space in a Higher Dimensional Steady State Universe
Ozgur Akarsu, Tekin Dereli
We investigate a class of cosmological solutions of Einstein's field equations in higher dimensions with a cosmological constant and an ideal fluid matter distribution as a source.…
A Comparison of the LVDP and ΛCDM Cosmological Models
Ozgur Akarsu, Tekin Dereli
We compare the cosmological kinematics obtained via our law of linearly varying deceleration parameter (LVDP) with the kinematics obtained in the ΛCDM model. We show that the LVDP…
A four-dimensional ΛCDM-type cosmological model induced from higher dimensions using a kinematical constraint
Ozgur Akarsu, Tekin Dereli
A class of cosmological solutions of higher dimensional Einstein field equations with the energy-momentum tensor of a homogeneous, isotropic fluid as the source are considered with…
