Abstract
The solvable model of a periodic array of quantum dots in a magnetic f ield is investigated. It is shown that in the case of square lattice a nd irrational flux the energy spectrum of a charged particle in the ar ray has a fractal structure. In the case of honeycomb lattice the exis tence of an additional splitting of magnetic bands related with lattic e geometry. The position of the Van Hove singularities is determined.
