I want to do my thesis about oscillations. I am a math student so I enjoy rigorous texts and hate sketchy ones. I am looking for a textbook or a good source that could help me with dynamical systems. What I mean is an introductory book for it.
For example I have enjoyed Real Mathematical Analysis by C.C. Pugh. I would greatly appreciate if someone could introduce me a book that could put everything about dynamical systems in perspective as good as it has been done in this book by Pugh (Pugh's is about analysis of course!).
Right now I started "Chaos: An Introduction to Dynamical Systems" by Alligood et al.
But I don't know if I am on the right track. So as a final sum-up:
- To be rigorous
- To cover introductory stuff(or maybe even
advanced too!!) - Good text: this probably means the ability of
writer to intuitively pass the message beside being rigorous.
Thanks in advance.
P.S. I already see this but I find it irrelevant to my question.

The book you started reading is good. However, despite that it treats some of more involved topics (as proof by exercises of Sharkovskii's theorem or stable and unstable manifold theorem), I still think that it is too wordy at the initial stage and skips a few very relevant points later. As a first introduction it is perfectly fine, but probably you'd like to see something more comprehensive.
There is another introductory book, which is quite rigorous and still accessible, and which goes really patient by introducing relevant concepts and notions: Hale and Kocak, Dynamics and Bifurcations. I think this book gives an ideal exposition to start reading graduate texts after it. This book however assumes that you already were exposed to differential equations (this is not a prerequisite in the book you are currently reading).
