      Abstract

      Using a fixed point theorem of general http://static-content.springer.com/image/art%3A10.1155%2F2010%2F494210/MediaObjects/13661_2010_Article_930_IEq1_HTML.gif -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.
