Oscillating dark energy: a possible solution to the problem of eternal acceleration
C. Rubano, P. Scudellaro, E. Piedipalumbo +1
We present a dark energy model with a double exponential potential for a minimally coupled scalar field, which allows general exact integration of the cosmological equations. The s…
Exponential Potentials for Tracker Fields
C. Rubano, P. Scudellaro, E. Piedipalumbo +2
We show that a general, exact cosmological solution, where dynamics of scalar field is assigned by an exponential potential, fulfils all the issues of dark energy approach, both fr…
Approximate angular diameter distance in a locally inhomogeneous universe with nonzero cosmological constant
M. Demianski, R. de Ritis, A. A. Marino +1
We discuss the general and approximate angular diameter distance in the Friedman-Robertson-Walker cosmological models with nonzero cosmological constant. We modify the equation for…
Noether symmetry in the higher order gravity theory
A. K. Sanyal, B. Modak, C. Rubano +1
Noether symmetry for higher order gravity theory has been explored, with the introduction of an auxiliary variable which gives the only correct quantum desccription of the theory,…
