Abstract

Existence results for two-point boundary value problems are established, the equation is not solved with respect to the high derivate, and the boundary conditions are nonlinear and full. The proofs are based on a variant of a basic theorem of Granas, Guenther and Lee. The a priori bounds needed for its application are obtained by the barrier strips technique.
