文摘In this paper we apply a cone theoretic fixed-point theorem proved by Krasnosel'skii to obtain sufficient conditions for the existence of positive solutions to some boundary value problems for a class of functional difference equations. We consider the case that the nonlinear term satisfies asvrnntoticallv linear growth.
