Abstract: By using the fixed-point index theorem, the optimal conditions of the existence of positive solutions to a class of the second-order discrete Neumann boundary value problems was obtained. It extended the previous results concerning the Neumann boundary value problems in ODE cases to that in the discrete cases.

Key words: Neumann boundary value problems, positive solutions, fixed-point index
