A basic text in differential-difference and functional-differential equations used by mathematicians and physicists in attacking problems involving the description and prediction of the behavior of physical systems. The subjects covered include the use of the Laplace transform to derive a contour-integral expression permitting a study of asymptotic behavior, the stability by solutions of linear and nonlinear differential-difference equations, and applications of these techniques to problems encountered in contemporary science and engineering.
