“…Very recently, the attention has shifted to problems on the infinite interval with linear functional conditions. There are a few papers to investigate the functional boundary value problems on the finite interval (see [7][8][9][10][11]). For example, in [8], Kosmatov and Jiang investigated second order functional problems with resonance of dimension one ⎧ ⎨ ⎩ x (t) = f (t, x(t), x (t)), 0 < t < 1, which improves the results of [6] and [7] in that respect as well and generalizes a number of recent works about two-point, three-point, multi-point, and integral boundary value problems.…”
