Bianchi type-I model with cosmic string in the presence of a magnetic field: spinor description

Abstract

A Bianchi type-I cosmological model in the presence of a magnetic flux along a cosmic string is investigated. A nonlinear spinor field is used to simulate the cosmological cloud of strings. It is shown that the spinor field simulation offer the possibility to solve the system of Einstein's equation without any additional assumptions. It is shown that the present model is nonsingular at the end of the evolution and does not allow the anisotropic Universe to turn into an isotropic one.

14 pages, 4 figures, new figus are added, singularity and isotropization process are discussed in detail
