The evolution of cosmological gravitational waves in f(R) gravity
Kishore N. Ananda, S. Carloni, P. K. S. Dunsby
We give a rigorous and mathematically clear presentation of the Covariant and Gauge Invariant theory of gravitational waves in a perturbed Friedmann-Lemaitre-Robertson-Walker unive…
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…
Cosmological dynamics of exponential gravity
M. Abdelwahab, S Carloni, P K. S. Dunsby
We present a detailed investigation of the cosmological dynamics based on gravity. We apply the dynamical system approach to both the vacuum and matter cases and obta…
Some remarks on the dynamical systems approach to fourth order gravity
S. Carloni, A. Troisi, P. K. S. Dunsby
Building on earlier work, we discuss a general framework for exploring the cosmological dynamics of Higher Order Theories of Gravity. We show that once the theory of gravity has be…
An analysis of the shear dynamics in Bianchi I cosmologies with -gravity
Jannie A. Leach, Peter K. S. Dunsby, Sante Carloni
We consider the case of -gravity and perform a detailed analysis of the dynamics in Bianchi I cosmologies which exhibit {\it local rotational symmetry} (LRS). We find exact so…
Cosmological dynamics of Scalar--Tensor Gravity
S Carloni, J A Leach, S Capozziello +1
We study the phase--space of FLRW models derived from Scalar--Tensor Gravity where the non--minimal coupling is and the effective potential is . Our analysis…
