. A system of fermions on a one-dimensional lattice, subjectto a periodic potential whose period is incommensurate with the latticespacing and verifies a diophantine condition, is studied. The Schwingerfunctions are obtained, and their asymptotic decay for large distances isexhibited for values of the Fermi momentum which are multiple of thepotential period.1. Introduction.1.1. The Static Holstein model [P, H] describes a system of fermions (electrons) in a linearlattice interacting...
