WebbThis book discusses delay and integro-differential equations from the point of view of the theory of functional differential equations. This book is a collection of selected papers … A functional differential equation is a differential equation with deviating argument. That is, a functional differential equation is an equation that contains a function and some of its derivatives evaluated at different argument values. Functional differential equations find use in mathematical models that assume a specified behavior or phenomenon depends on the present as well as the past state of a system. In other …
