Abstract

Parametric expansions of dispersion laws are obtained by the method of charged corepresen-tations in the quadratic approximation in components of the wave number vector. The possible multiple degeneracies and zero-slope energy surfaces in the neighborhood symmetry points of the crystal Brillouin zone are obtained for the space groups D 4h 1 -D 4h 16 .
