Existence of Positive Solutions for Second-Order Difference Equation with Discrete Boundary Value Problem

We study the existence of positive solutions to the three
points difference-summation boundary value problem. We show the
existence of at least one positive solution if f is either superlinear or
sublinear by applying the fixed point theorem due to Krasnoselskii
in cones.
