摘　　要：This paper presents sufficient conditions for the existence of positive solutions to some second-order system of difference equations subject to some boundary conditions. We show that it has at least three positive solutions under some assumptions by applying the fixed point theorem.This paper presents sufficient conditions for the existence of positive solutions to some second-order system of difference equations subject to some boundary conditions.
