Late time behaviour of closed isotropic models in second order gravity theory |
Homogeneous and isotropic models are studied both in the Jordan and in the Einstein frame of the second order gravity theory. The late time evolution of the models is analyzed with the methods of the dynamical systems. The normal form of the dynamical system has periodic solutions for a large set of initial conditions. This implies that an initially expanding closed isotropic universe may exhibit oscillatory behavior. |
