Functional Differential Equations with Infinite Delay

In the theory of functional differential equations with infinite delay, there are several ways to choose the space of initial functions (phase space). Diverse (duplicated) theories arise, according to the choice of phase space. This book is intended as a reference work on the theory of equations with infinite delay, which may be used as a textbook for a graduate course. It is assumed that readers already have a working knowledge of applied analysis, including linear algebra and functional analysis.
