Existence of solutions to higher-order discrete three-point problems. <i>Electronic Journal of Differential Equations, 2003</i>(40), pp. 1-7.1072-6691https://hdl.handle.net/10877/12801We are concerned with the higher-order discrete three-point boundary-value problem (∆n x)(t) = ƒ(t, x(t + θ)), t1 ≤ t ≤ t3 - 1, -τ ≤ θ ≤ 1 (∆ix)(t1) = 0, 0 ≤ i ≤ n - 4, n ≥ 4 α(∆n-3x)(t) - β(∆n-2x)(t) = η(t), t1 - τ - 1 ≤ t ≤ t1 (∆n-2x)(t2) = (∆n-1x)(t3) = 0. By placing certain restrictions on the nonlinearity and the distance between boundary points, we prove the existence of at least one solution of the boundary value problem by applying the Krasnoselskii fixed point theorem.Text7 pages1 file (.pdf)enAttribution 4.0 InternationalDifference equationsBoundary-value problemGreen's functionFixed pointsConeArticle
