Dynamical dark energy in models with evolution close to CDM
Saikat Chakraborty, Charlotte Louw, Peter K. S. Dunsby +2
In this communication we address whether or not there is an equivalence between the kinematical and dynamical descriptions of the spatially flat CDM model. We address this by i…

A model-independent compact dynamical system formulation for exploring bounce and cyclic cosmological evolutions in gravity
A. S. Agrawal, Charlotte Louw, Saikat Chakraborty +1
Using the dynamical systems approach together with the cosmographic parameters, we present a model-independent dynamical system formulation for cosmology in f(R) gravity. The formu…
