Abstract

We study the behavior of all eigenvalues for boundary value problems of fourth-order difference equations Δ4y i = λai+2yi+2, -1≤in-2, y0 = Δ2y-1 = Δy n = Δ3yn-1 = 0, as the sequence varies. A comparison theorem of all eigenvalues is established for two sequences and with a j b j , 1 ≤ jn, and the existence of positive eigenvector corresponding to the smallest eigenvalue of the problem is also obtained in this paper.
