where wlr . . . w, is a given set of frequencies and the Fourier coefficients, c k , , . k, = ck, satisfy 8, I c,12 -; r. The question is, For what values of E does equation 1 have two linearly independent quasi-periodic solutions? This problem was first treated in the case where n > 1 by Dinaburg and Sinai.' They proved that, under the additional assumptions that ( A , ) the frequencies w , . . . . on satisfy the inequalities
