Harper's operator is the self-adjoint operator on 12(7/) defined by Ho,o~(n) = ~(n + 1) + se(n -1 ) + 2 cos(2zr(n0 + (p))~(n) (~ ~ l 2 (7/), n 6 7/, 0, (p c [0, I ]). We first show that the determination of the spectrum of the transition operator on the Cayley graph of the discrete Heisenberg group

It is shown that the isotropic Heisenberg model can be analysed in terms of a random walk on the permutation group. This approach makes it intuitively clear why the Heisenberg model exhibits long range order or ferrogmagnetic behavior in three dimensions and not in two and one dimensions. This appro
