Abstract
Using the supersymmetry method an exact analytic formula for the integrated density of states of a disordered half‐filled Peierls‐Fröhlich system is derived. All kinds of disorder which can be handled in the continuum approximation, i. e. forward and backward scattering as well as (alternating) bond disorder, are included. Special cases are discussed.Keywords
