摘要
In this paper we deal with the four-point singular boundary value problem {(phi(p)(u'(t)))' + q(t) f(t, u(t), u'(t)) = 0, t is an element of (0, 1), u'(0) - alpha u(xi) = 0, u'(1) + beta u(eta) = 0, where phi(p)(s) = |s|(p-2) s, p > 1, 0 < xi < eta < 1, alpha, beta > 0, q is an element of C[0, 1], q(t) > 0, t is an element of (0, 1), and f is an element of C([0, 1] x (0,+infinity) x R, (0,+infinity)) may be singular at u = 0. By using the well-known theory of the Leray-Schauder degree, sufficient conditions are given for the existence of positive solutions.
