Spatial structures as a result of a modulational instability are obtained in the integrable discrete nonlinear Schro Β¨dinger equation (Ablowitz-Ladik equation). Discrete slow space variables are used in a general setting and the related finite differences are constructed. Analyzing the ensuing equat
