I was reading Baby Rudin for Real Analysis and wanted to explore Topology a little deeper. I bought George Simmons' Introduction to Topology and Modern Analysis and found myself liking it. I am having some problems every once in a while with prerequisites.
How much Set theory do I need to learn before diving into the aforementioned book?
Also, the book is divided into 3 parts : Topology, Operators and Algebras of Operators.
Till where can I trot with a good understanding of SV Calculus?
