Dynamics of a Homogeneous and Isotropic Space in Pure Cubic f(R) Gravity

We consider a possible ways of the dynamics homogeneous and isotropic space described by FLRW metric in framework cubic f(R) gravity absence matter. This article points an method for limiting parameters extended models. propose develop models based on metrics various model simplest example. The influence initial conditions further are discussed. can be limited 1) slow growth space, 2) instability, 3) divergence with inflationary scenario.
