this book is lacking of any real mathematical rigor, plus it lacks valuable theorems from linear algebra that someone i know pointed out in an earlier edition of this book, which has since been taken out by devaney. any serious mathematician (applied or otherwise) who wants real mathematical rigor should look elsewhere, or at least find an earlier edition of the book without devaney.
Sadly enough, this has been my latest good read in a few months. I though it deserved my recommendation since I've seen it more than my girlfriend this quarter.
