Boundary Value Problems 2010, 2010:494210  doi:10.1155/2010/494210

Published: 29 July 2010


Using a fixed point theorem of general -concave operators, we present in this paper criteria which guarantee the existence and uniqueness of positive solutions for two classes of nonlinear perturbed Neumann boundary value problems for second-order differential equations. The theorems for Neumann boundary value problems obtained are very general.
