Dynamical System of Gauss-Bonnet Model with Vector Field

Abstract

Modifying the Einsteins gravity is one of the interesting proposal to explain the dark energy that dominated our universe today. We investigated Gauss-bonnet model with vector field in the action function and we show the influence of the vector field to the density parameters of the model with a dynamical system approach. Parameter β that contributed by vector field give change to the evolution of density parameters. The model also can represent the condition of the present universe which dominated by dark energy.
