Advanced Mathematical Methods for Scientists and Engineers I - Asymptotic Methods and Perturbation Theory (Bender Carl M.)(Pevná vazba)

Intended for graduate students and advanced undergraduates, this book gives a clear, practical and self-contained presentation of the methods of asymptotics and perturbation theory for obtaining approximate analytical solutions to differential and difference equations. These methods allow one to analyze physics and engineering problems that may not be solvable in closed form and for which brute- force numerical methods may not provide useful
