Spherically symmetric ADM gravity with variable G and Lambda(c)
Giampiero Esposito, Claudio Rubano, Paolo Scudellaro
This paper investigates the Arnowitt--Deser--Misner (hereafter ADM) form of spherically symmetric gravity with variable Newton parameter G and cosmological term Lambda(c). The Newt…
Noether symmetry approach to scalar-field-dominated cosmology with dynamically evolving G and Lambda
Alfio Bonanno, Giampiero Esposito, Claudio Rubano +1
This paper studies the cosmological equations for a scalar field Phi in the framework of a quantum gravity modified Einstein--Hilbert Lagrangian where G and Lambda are dynamical va…
Noether symmetry approach in matter-dominated cosmology with variable G and Lambda
Alfio Bonanno, Giampiero Esposito, Claudio Rubano +1
In the framework of renormalization-group improved cosmologies, we use the Noether symmetry approach to get exact and general integration of the matter-dominated cosmological equat…
Testing a quintessence model with CMBR peaks location
D. Di Domenico, C. Rubano, P. Scudellaro
We show that a model of quintessence with exponential potential, which allows to obtain general exact solutions, can generate locations of CMBR peaks which are fully compatible wit…
Quintessence or Phoenix?
C. Rubano, P. Scudellaro
We show that it is impossible to determine the state equation of quintessence models on the basis of pure observational SNIa data. An independent estimate of is necessary.…
