Resumo
We consider a chiral cosmological model in the framework of Einstein–Gauss–Bonnet cosmology. Using a decomposition of the latter equations in such a way that the first chiral field is responsible for the Einstein part of the model while the second field together with the kinetic interaction is connected with the Gauss–Bonnet part of the theory, we find new exact solutions for the 2-component chiral cosmological model with and without a kinetic interaction between the fields.
