Description
Dynamical system formulation is an important qualitative tool now widely used in
cosmology to understand the cosmological solution space of a theory. A number of
dynamical system formulations have been proposed over the last few years to analyse
cosmological solutions in f(R) gravity. I will try to give a brief introduction to the
di↵erent approaches, presenting them in a chronological order as they appeared in
the history of the relevant scientific literature. I will particularly illuminate how the
shortcoming(s) of an existing formulation encouraged the development of an alternative
formulation. I will also try to emphasize the utility of the dynamical system formulation
in to study various aspects of cosmological perturbations.
