Existence Theory for Nonlinear Integral and Integrodifferential Equations

This text presents an account of many topics of interest in the theory of nonlinear ordinary differential equations. They include fixed point theory, periodic problems, lower and upper surfaces, positone and semi-positone problems, singular equations, limit circle problems, finite and infinite interval problems, and impulsive differential equations. In addition many important applications are presented to complement the theory. This work should be of interest to theoretical and applied mathematicians and graduate students in the above disciplines.
