Quadratic corrections to the Lagrangian density of the gravitational field and asymptotic analysis. |
Abstract _ |
It was shown by T.V. Ruzmaikina and A.A. Ruzmaikin that the solutions coming from a generalized Lagrangian density with quadratic corrections of the gravitational field, within the framework of a homogeneous and isotropic cosmological model and which asymptotically go over into the Friedmann solution, are singular at t=0. We investigate the generality of these solutions. |
