The present book builds upon an earlier work of J. Hale, "Theory of Func tional Differential Equations" published in 1977. We have tried to maintain the spirit

Since the publication of my lecture notes, Functional Differential Equations in the Applied Mathematical Sciences series, many new developments have occurred. A

This volume provides an introduction to the properties of functional differential equations and their applications in diverse fields such as immunology, nuclear

In the theory of functional differential equations with infinite delay, there are several ways to choose the space of initial functions (phase space); and diver

Abstract semilinear functional differential equations arise from many biological, chemical, and physical systems which are characterized by both spatial and tem
