Abstract

In this paper, we apply an extension of the Leggett-Williams fixed point theorem to the second order difference equation ∆2u(k)+f(u(k+1)) = 0, k ∈ {0, 1, . . . , N}, satisfying the anti-periodic boundary conditions u(0) + u(N + 2) = 0, ∆u(0) + ∆u(N +1) = 0. Two important results of this paper involve providing the Green’s function for −∆2u(k) = 0 satisfying u(0) + u(N + 2) = 0, ∆u(0) + ∆u(N + 1) = 0 and showing this Green’s function satisfies a concavity like property. An example is also given.
