Scientific Achievements

The unified approach to the problem of motion in relativistic physics was proposed. It allowed basing the universal form of equations of motion of second type and deduced the self-consistent equations of motion for N colored massive particles at first (cosmic chromodynamics); the improved equations of motion for charged and magnetize massive particles; equations of motion for N massive bodies of finite sizes in the monad frame of references; self-consistent approach to N cosmic strings with application to the case of two oscillating strings; new model of the nonlinear cosmic string.

Some important results were achieved in cosmology – Jeans equation generalization for baryonic and nonbaryonic substrates presence; new many-component model of cosmic lenses; high resolution gravitational lens model; Cherenkov radiation in the galaxies dark matter haloes; the induced rotational effect in de-Sitter and Friedmann cosmology; the vacuum conception of the galaxies’ initial rotation.

Now precise attention is sparing to basing the concept of Universe global rotation – precalculation the “axis of evil” orientation; Universe differentially rotation at its main cosmological epochs.
