When general topological spaces are too broad, we often add more axioms to make them "nice." This section covers:

This advanced section revisits the concept of convergence. Since sequences are insufficient for many abstract spaces, the text introduces nets (generalized sequences) and filters as more powerful tools for studying convergence, continuity, and compactness in their most general forms.

"The style of writing is student-friendly, the topics are nicely motivated, (counter-)examples are given where they were needed, many diagrams provided, and the chapter exercises relevant..." "An excellent book to start Topology, this book is followed almost in every good institute. Book has beautifully written proofs with very good problems." Topology By H.k. Pathak Pdf Download UPD
