Abstract

Density of state calculation performed previously for the Harper-equation by Wannier, Obermair and Ray [Phys. Status SolidiB93, 337 (1979)] are updated analytically and numerically. One considers both the influence of anisotropy and commensurability parameters. The main point of our generalization is to account for a multiplicity parameter describing the amount of coprime realizations of the commensurability parameter.
