Anisotropic cosmological solutions in $$R + R^2$$ R+R2 gravity
Abstract In this paper we investigate the past evolution of an anisotropic Bianchi I universe in $$R+R^2$$ R+R2 gravity. Using the dynamical system approach we show that there exists a new two-parameter set of solutions that includes both an isotropic “false radiation” solution and an anisotropic ge...
