Abstract

In this paper, we consider the following second-order ordinary differential equation x" = f(t,x(t),x'(t)) + e(t), t ∈ (0, 1), (E) subject to one of the following boundary value conditions: x(0) = ∑ αix(ξi), x(1) = βx(η), (B1) x(0) = ∑ αix(ξi), x'(1) = βx'(η), (B2) x'(0) = ∑ αix'(ξi), x(1) = βx(η), (B3) x'(0) = ∑ αix'(ξi), x'(1) = βx'(η), (B4) where αi (1≤i≤m-2), β ∈ R, 0 1 2 m-2 i's have no the same sign, some existence results are given for (E) with boundary conditions (B1), (B2), (B3), (B4) at resonance case. We also give some examples to demonstrate our results.
