Abstract: | A one-dimensional system of electrons on a lattice, interacting with a periodic potential, with period incommensurate with
the lattice spacing and satisfying a Diophantine condition, is considered in the case of strong interaction. The Schwinger
functions are computed and their asymptotic behaviour is studied, proving Anderson localization. The decay of the Schwinger
functions is shown to depend critically on the value of the chemical potential.
