Topology Without Tears꞉ Including a Graduate Course on Topological Groups

"Topology has several different branches — general topology (also known as point- set topology), algebraic topology, differential topology and topological algebra — the first, general topology, being the door to the study of the others. I aim in this book to provide a thorough grounding in general topology." Contents 0.
