I'm taking a course in dynamical systems and I'm struggling to grasp some of the concepts. The instructor only occasionally reference the textbook I'm using, which is Differential Equations, Dynamical Systems, and An Introduction to Chaos 2nd Ed. (By Hirsch, Smale, and Devaney). I'm looking for addtional books/resources on this topic. Ideally, I'm looking for something that serves as a good introduction to the subject of dynamical systems, so that I can easily understand the concepts. Addtionally, it would be nice after the concept explanation it would go into slightly more advanced applications. The more examples there are the better. Proofs are nice but I don't really care too much about them - it's more the application and east of understanding I care about. any suggestions and ideas would be welcome.
