My book "Asymptotic Expansions for Ordinary Differential Equations" published in 1965 is out of print. In the almost 20 years since then, the subject has grown

Fully developed theory is extant, and can justifiably be referred to as classical, for the determination of the asymptotic forms of the solutions of a different

In this book the author presents the dynamical systems in infinite dimension, especially those generated by dissipative partial differential equations. This boo
