We studied the existence of positive solutions of the boundary value problem for a nonlinear finite fractional difference equation .First ,according to fractional difference equation and its boundary conditions ,we constructed the Green’s function and analyzed its properties .Then ,by using the Krasnosel’skii fixed point theorem we obtained sufficient conditions for the existence of positive solutions of the boundary value problem for the nonlinear finite difference equation .
