| Abstract: | Using the method of charged corepresentations 1], we obtain parametric expansions of dispersion laws in wave vector components in the quadratic approximation, possible degeneracies, and vanishing slopes of energy surfaces close to symmetry points of the Brillouin zone of class C4h crystals with a simple tetragonal lattice. |
