I have just begun my first dynamical systems class, and I would like to try out the advice in the top answer [here](https://math.stackexchange.com/questions/1844354/what-is-the-correct-way-to-self-learn-from-a-textbook?rq=1). To summarize, the answer suggests that when studying a new field, one should look at the original papers, and supplement it with modern material.

My class is roughly following *Introduction to Dynamical Systems* by Brin and Stuck. We are starting in the second chapter, which is about topological dynamics (it is only 20 pages, but very dense). I was wondering if you could please recommend me some authors/papers which started the field?

Thank you very much.
