MAA Review[Reviewed by Luiz Henrique de Figueiredo, on 05/12/2012]
This is Dover edition of the 1996 original, with the same nice typesetting. The book is also available in standard LaTeX typesetting at the author’s web site, which also contains a solution guide.
The book is true to its title: the aim is to take dynamical systems to a wide audience of students in engineering, science, economics, computer science, mathematics, etc. It has very few prerequisites: calculus and linear algebra, but no differential equations. The focus is on ideas, not on formal theorems and proofs.
In all, I think the author succeeds quite well in his goal. Certainly, any student that reads this book seriously will learn a lot of non-trivial interesting mathematics. Indeed, while the prose is quite agreeable, this is not a watered-down presentation. It discusses advanced results, such as Liapunov functions, the Poincaré-Bendixson theorem, symbolic dynamics, Sharkovskii’s theorem, and even proves a special case of Li and Yorke’s theorem that “Period Three Implies Chaos,” a famous Monthly article. (There are not many references, though. While this might have been a hindrance in 1996, today it’s just fine: searching the web for these results is quite easy and will probably lead the curious student to further results.)
I have only two minor quibbles: Chapter 5 on fractals, while nicely done, breaks the flow of presentation, from real quadratic dynamical systems in Chapter 4 to complex ones in Chapter 6. This last chapter is also too short, when compared with the others. Of course, complex dynamical systems is a huge subject and there are plenty of excellent introductory books, such as Devaney’s Chaos, Fractals and Dynamics: Computer Experiments in Mathematics. But these are just two minor points. The book is very nice. I’ve enjoyed reading it and I’m positive that others will as well.
