Abstract |
The Kantowski-Sachs cosmological model sourced by a Skyrme field and a cosmological constant is considered in the framework of General Relativity. The choice of the spacetime metric and the hedgehog ansatz with a constant radial profile function $\alpha = \pi/2$ allow to simplify the Einstein-Skyrme system. Using dynamical system techniques, a qualitative analysis of the cosmological equations is presented. Physically interesting features of the model such as isotropization, bounce and recollapse are discussed. |
