摘要
We study the existence of positive solutions of the nonlinear boundary value problem u((4))(t) = f(t, u(t), u ''(t)), t is an element of (0, 1), u(0) = u(1) = u ''(0) = u ''(1) = 0, which is not necessarily linearizable. Our approaches are based on Krein-Rutman theorem, topological degree theory and global bifurcation techniques. (C) 2009 Elsevier Ltd. All rights reserved.
