Introduction to the Modern Theory of Dynamical Systems (Encyclopedia of Mathematics and its Applications)
"...well written and clear...a valuable reference for engineers and mechanicians."   H.W. Haslach Jr., Applied Mechanics Reviews"The book is a pleasure to read."   Edoh Amiran, Mathematical Reviews"The notes section at the end of the book is complete and quite helpful.  There are hints and answers provided for a good percentage of the problems in the book.  The problems range from fairly straightforward ones to results that I remember reading in research papers over the last 10-20 years....I recommend the text as an exceptional reference..."
