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 of that book and have …

This monograph is devoted to the mathematical theory of continuous, deterministic,
nonlinear models of populations with age structure. There is a long history and extensive …

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

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

It is the purpose of these notes to describe the theory of Hale and Kato for functional
differential equations based on a space of initial data which satisfy some very reasonable …

THE THEORY of equations with delay has been considerably developed during the past 30
years. The first book dedicated to this subject has been published by Myshkis [180], in 1951 …

The goal of this work is the development of an existence and stability theory for a class of Itô
stochastic functional (hereditary) differential equations. These equations are related to …

FUNCTIONAL differential neutral-type equations are of great interest in theoretical
investigations and form an important class as regards their applications. This class of …

In this paper, the stability and stabilization problems for nonlinear Volterra integrodifferential
equations with unlimited delay are considered. The development of the direct Lyapunov …

The author introduces the concept of a map with memory associated to a given map f and to
a normalized weight sequence P. The stabilization properties of maps with memory are …
