Long-wave low-frequency oscillations are described in a Wigner crystal by generalization of the reverse continuum model for the case of electronic lattice. The internal self-consistent long-wave electromagnetic field is used to describe the collective motions in the system. The eigenvectors and eigenvalues of the obtained system of equations are derived. The velocities of longitudinal and transversal sound waves are found.

    We consider the matter effect on three flavor neutrino mixing. We write an analytical description of neutrino mixing angle in matter based on the perturbation approach. The matter effect is ignored for reactor neutrino analysis because the path length is very small. Matter effect play important...
