Scalar–tensor cosmology with R^-1 curvature correction by Noether symmetry
سال: 2008
خلاصه:
We discuss scalar–tensor cosmology with an extra R^-1 correction by the Noether symmetry approach.
The existence of such a symmetry selects the forms of the coupling ω(ϕ), of the potential V (ϕ) and
allows ...
Exact cosmological solutions from Hojman conservation quantities
سال: 2013
خلاصه:
We present a new approach to find exact solutions for cosmological models. By requiring the existence of
a symmetry transformation vector for the equations of motion of the given cosmological model (without
using ...
