Two-Point Boundary Value Problems: Lower and Upper Solutions

This book introduces the method of ordinary differential equations. This method is known to be both easy and the second-order boundary value problems. Extra large details of the subject. A concern with the use of a method with a degree of theory, with variational methods and positive operators. The second half of the book concerns applications. This is a part of the problematic problem. The difference between the differential equations and functional differential equations. A detailed history of the problem.

· Presents the fundamental features of the method
· Construction of lower and upper solutions in problems
· Working applications and illustrated theorems by examples
