摘要：In this paper, some new existence criteria of positive solution to thefollowing second-order discrete boundary value problem\[-\Delta \left[ p(n-1)\Delta y(n-1)\right] +q(n)y(n)=f(n,y(n)), \qquad n\in[1,N],\]\[y(0)=y(N), \qquad p(0)\Delta y(0)=p(N)\Delta y(N)\]is obtained by using the upper and lower solution method.
