The dielectric constant of the plasma in an electric field of random waves of moderate intensity was investigated. In the framework of deformation theory of general relativity investigated modification of the theory of cosmological perturbations. In a wide range of values of deformation parameter, there is a special transition from the regime of modified gravity to the regime of general relativity in the evolution of scalar perturbations. A new mechanism of generation of high velocity of pulsars associated with the possibility of existence of axial currents in the central regions of neutron stars with strong magnetic fields was suggested.
