Because the theory of equations with delay terms occurs in a variety of contexts, it is important to provide a framework, whenever possible, to handle as many c

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

With neutral differential equations, any lack of smoothness in initial conditions is not damped and so they have proven to be difficult to solve. Until now, the

In recent years there has been a resurgence of interest in the study of delay differential equations motivated largely by new applications in physics, biology,

Examines developments in the oscillatory and nonoscillatory properties of solutions for functional differential equations, presenting basic oscillation theory a
