Spherical symmetry in -gravity
S. Capozziello, A. Stabile, A. Troisi
Spherical symmetry in gravity is discussed in details considering also the relations with the weak field limit. Exact solutions are obtained for constant Ricci curvature sca…
The evolution of density perturbations in f(R) gravity
S. Carloni, P. K. S. Dunsby, A. Troisi
We give a rigorous and mathematically well defined presentation of the Covariant and Gauge Invariant theory of scalar perturbations of a Friedmann-Lemaitre-Robertson-Walker univers…
Spherically symmetric solutions in f(R)-gravity via Noether Symmetry Approach
S. Capozziello, A. Stabile, A. Troisi
We search for spherically symmetric solutions of f(R) theories of gravity via the Noether Symmetry Approach. A general formalism in the metric framework is developed considering a…
Curvature and Torsion Quintessence
S. Capozziello, S. Carloni, G. Lambiase +2
The issues of quintessence and cosmic acceleration can be discussed in the framework of higher order curvature and torsion theories of gravity. We can define effective pressure and…
