Abstract
In this paper, a parametrically driven discrete nonlinear Schrodinger equation will be considered for defocusing case. Analytical and numerical¨ calculations will be performed to determine the existence and stability of intersite dark discrete solitons admitted by discrete nonlinear Schrodinger¨ equation. It will be shown that a parametric driving can stabilizes intersite discrete dark solitons. Stability windows of all the fundamental solitons will be presented and approximations to the onset of instability will be derived using perturbation theory, with accompanying numerical results.
