Abstract
We establish the existence of at least three positive solutions for the second-order three-point discrete boundary value problem:
where f is continuous, T≥3 and n∈{2,…,T−1} are two fixed positive integers, constant α>0 such that α n<T+1. Under suitable conditions, we accomplish this by using the property of the associate Green’s function and Leggett-Williams fixed point theorem.
