Cosmologies from Nonlinear Multidimensional Gravity with Acceleration and Slowly Varying G
We consider multidimensional gravity with a Lagrangian containing the Ricci tensor squared and the Kretschmann invariant. In a Kaluza-Klein approach with a single compact extra space of arbitrary dimension, with the aid of a slow-change approximation (as compared with the Planck scale), we build a class of spatially flat cosmological models in which both the observed scale factor a(τ) and the e...
متن کاملViscous Cosmologies with Variable G and Λ in R Gravity
We study evolution of a flat Friedmann-Robertson Walker universe filled with a bulk viscous cosmological fluid in a higher derivative theory of gravity in the presence of time varying gravitational and cosmological constant. Cosmological models admitting both power-law and exponential expansions are explored here in the presence of imperfect fluid described by full Israel and Stewart theory. We...
متن کاملMultidimensional Cosmology with Anisotropic Fluid: Acceleration and Variation of G
A multidimensional cosmological model describing the dynamics of n+1 Ricci-flat factor-spaces Mi in the presence of a one-component anisotropic fluid is considered. The pressures in all spaces are proportional to the density: pi = wiρ , i = 0, ..., n . Solutions with accelerated expansion of our 3-space M0 and small enough variation of the gravitational constant G are found. These solutions exi...

متن کاملEscape Time from Potential Wells of Strongly Nonlinear Oscillators with Slowly Varying Parameters
The effect of negative damping to an oscillatory system is to force the amplitude to increase gradually and the motion will be out of the potential well of the oscillatory system eventually. In order to deduce the escape time from the potential well of quadratic or cubic nonlinear oscillator, the multiple scales method is firstly used to obtain the asymptotic solutions of strongly nonlinear osc...
