Positive solutions for a class of boundary-value problems with integral boundary conditions
This paper investigates the existence and multiplicity of positive solutions for a class of nonlinear boundary-value problems of fourth-order differential equations with integral boundary conditions. The arguments are based upon a specially constructed cone and the fixed-point theory in cone. The nonexistence of positive solutions is also studied. (c) 2009 Elsevier Ltd. All rights reserved.
