Abstract
The work of Kohn is generalized to more than one dimension for a finite-band model by a simple algebraic procedure. Some results not previously derived for more than one dimension are obtained. The differences between the analytic properties of the model and those of the complete Hamiltonian are briefly discussed.Keywords
