Abstract
In this paper, we apply a cone theoretic fixed-point theorem and obtain suf ficient conditions for the existence of positive solutions to some boundary value problems for a class of functional difference equations. We consider analogues of sublinear or superlinear growth in the nonlinear terms. (C) 2 001 Elsevier Science Ltd. All rights reserved.
