Cosmological dynamics of fourth-order gravity: A compact view
We construct a compact phase space for flat Friedmann-Lema\^{\i}tre-Robertson-Walker spacetimes with standard matter described by a perfect fluid with a barotropic equation of state for general $f(R)$ theories of gravity, subject to certain conditions on the function $f$. We then use this framework to study the behavior of the phase …
