Bloch solutions of the difference Schrödinger equation with periodic complex potential on the real line are discussed. The case where the spectral parameter is outside the spectrum of the corresponding Schrödinger operator is considered.
Keywords: difference equations on the real line, periodic coefficients
Mots-clés : Bloch solutions.
