<正> Ablowitz and Ladik have derived two kinds of discrete forms of A. K. N. S.-Zakharov-Shabat eigenvalue problems—one includes two potentials, while the other includes four potentials. This paper discusses the relations between these two kinds of discrete Ablowitz-Ladik eigenvalue problems in full.
