Özet

In this paper, we investigate the analytical properties of the Jost solutions of non-self-adjoint system of difference equations of first order. Using the analytical properties of the Jost solutions, we also study the discrete spectrum of this system. (C) 2004 Elsevier Ltd. All rights reserved.
