Perturbation growth and cosmic microwave background anisotropies in the stringlike matter-dominated universe.

The growth of small perturbations and the temperature correlation function of cosmic background radiation induced by the perturbations in the isotropic and homogeneous universe with arbitrary spatial curvature, filled with nonrelativistic and so-called string-like matter is calculated. It is shown that both magnitudes are insensitive to the eventual existence of the string-like matter in the universe. The widespread opinion that the string-like matter dominated universe suppresses the growth of perturbation is verified.
