PHASE SPACE OF ANISOTROPIC R<sup>n</sup> COSMOLOGIES
PHASE SPACE OF ANISOTROPIC R<sup>n</sup> COSMOLOGIES
We construct general anisotropic cosmological scenarios governed by an $f(R)=R^n$ gravitational sector. Focusing then on some specific geometries, and modelling the matter content as a perfect fluid, we perform a phase-space analysis. We analyze the possibility of accelerating expansion at late times, and additionally, we determine conditions for the parameter …
