The singular boundary value problem is studied in this paper.The singularity may appear at t = 0 and the function g may be superlinear at u = ∞ and change sign. The existence of solutions is obtained via an upper and lower solutions method.

This paper is concerned with the fourth-order four-point boundary value problem where η, ξ ∈ (0, 1) and a, b ≥ 0. The upper and lower solution method and a new maximum principle are employed to establish existence results and we release the increasing condition imposed on f (t, u, v).
