Unified dark matter and dark energy description in a chiral cosmological model

Original · EN

We show the way of dark matter and dark energy presentation via ansatzs on the kinetic energies of the fields in the two-component chiral cosmological model. To connect a kinetic interaction of dark matter and dark energy with observational data the reconstruction procedure for the chiral metric component h₂₂ and the potential of (self)interaction V has been developed. The reconstruction of h₂₂ and V for the early and later inflation have been performed. The proposed model is confronted to ΛCDM model as well.
