Abstract |
The application of a chiral cosmological model (CCM), as a non-linear sigma model with the potenial of (self)interactions, in cosmology will be presented. Cosmological perturbations, power spectrum and culculation of spectral parameters without reference to slow-roll approximation will be discussed. Description of the dark sector fields as the chiral fields of CCM and influence of internal space parameters for shifting of the cosmological perturbations will be discussed as well. Superpotential method for exact solutions construction for canonical, phantom and tachyon fields will be described. Applications of CCM for Emergent Universe scanario, for wormholes investigations and comparision with a multy-fields model will be demonstrated. |
