FRW-metric and Friedmann equations in a generalized cosmological model

A generalized model of space-time is given, taking into consideration the anisotropic structure of fields which are depended on the position and the direction (velocity). In this framework a generalized FRW-metric and Friedmann equations are studied. A long range vector field of cosmological origin...

Description
Summary:A generalized model of space-time is given, taking into consideration the anisotropic structure of fields which are depended on the position and the direction (velocity). In this framework a generalized FRW-metric and Friedmann equations are studied. A long range vector field of cosmological origin is considered in relation with the physical geometry of space-time in which Cartan connection has a fundamental role.
