The analysis of evolution of perturbations in ionized fractions, the calculation of power spectrum for the number density perturbations of free electrons at the recombination epoch. Determination of cosmological model parameters and constraints on dark energy models confrontation of theoretical predictions with novel observational data on global propeties of universe, its large-scale structure and anisotropy of cosmic microwave bachground.
