WebThis is not true for crystal lattice systems in which the primitive lattices are not mutually orthogonal. When in doubt, just calculate using the full equations from earlier. The reciprocal lattice is also a lattice (and if the direct lattice is primitive, then so is the reciprocal), and WebThe theory of tetragonal curves is established and first applied to the study of algebro-geometric quasi-periodic solutions of discrete soliton equations. Using the zero-curvature equation and the discrete Lenard equation, we derive the hierarchy of Bogoyavlensky lattice 2(3) equations associated with a discrete $$4\\times 4$$ 4 × 4 matrix spectral …
