摘要

In this paper, we consider the following second-order ordinary differential equation x" = f (t, x(t), x'(t)) + e(t), t is an element of (0, 1), (E) subject to one of the following boundary value conditions: x(0) = Sigma(i=1)(m-2)alpha(i)x(xi(i)), x(1) = betax(eta), (B-1) x(0) = Sigma(i=1)(m-2)a(i)x(xi(i)), x'(1) = betax'(eta), (B-2) x'(0) = Sigma(i=1)(m-2)alpha(i)x'(xi(i)), x'(1) = betax'(eta), (B-3) x'(0) = Sigma(i=1)(m-2)alpha(i)x'(xi(i)), x'(1) = betax'(eta), (B-4) where alpha(i) (1 less than or equal to i less than or equal to m-2), betais an element ofR, 0 < xi(1) < xi(2) < ... < xi(m-2) < 1, 0 < eta < 1. When all the alpha(i)'s have no the same sign, some existence results are given for (E) with boundary conditions (B-1), (B-2), (B-3), (B-4) at resonance case. We also give some examples to demonstrate our results. (C) 2002 Elsevier Science Inc. All rights reserved. [References: 20]
