Topological methods in the study of boundary value problems / Pablo Amster.

Shooting Type Methods -- The Banach Fixed Point Theorem -- Iterative Methods -- The Schauder Theorem and Applications -- Topological Degree: An Introduction

This textbook is devoted to the study of some simple but representative nonlinear boundary value problems by topological methods. The approach is elementary, with only a few model ordinary differential equations and applications, chosen in such a way that the student may avoid most of the technical difficulties and focus on the application of topological methods.
