Krishna’s Topology , primarily authored by J. N. Sharma and J. P. Chauhan, is a cornerstone textbook published by Krishna Prakashan Media for honors and postgraduate students across Indian universities. Spanning over 600 pages, the book is designed to align with the UGC curriculum, providing an exhaustive exploration of both general and algebraic topology. Core Conceptual Framework
The text serves as a bridge between foundational mathematical concepts and advanced abstract reasoning. It begins with essential set theory and real number properties before delving into the specialized domains of topology:
Topological Spaces: Detailed definitions of discrete, indiscrete, and metric topologies.
Global Properties: In-depth coverage of compactness, connectedness, and completeness, including critical theorems like Urysohn’s lemma and metrizability.
Algebraic Transition: The book uniquely integrates algebraic aspects, guiding students through homotopy, homology, and cohomology groups to understand topological spaces through an algebraic lens. Educational Value and Pedagogy
Reviewers and educators value the Krishna publication for its "self-study" friendly structure. Its pedagogical highlights include: topology krishna publication pdf download exclusive
Active Learning: Many editions separate theorem formulations from their proofs, encouraging students to think critically before reaching the solution—effectively functioning as both a textbook and a problem book.
Comprehensive Problem Sets: The text is renowned for its vast collection of routine and advanced problems, often accompanied by hints, making it a "supreme" choice for competitive exams like NET, GATE, and SET.
Geometric Motivation: Concepts are frequently motivated through geometric analogies, helping beginners overcome the initial difficulties of abstract topological theory. Availability and Digital Access
While the physical paperback remains a popular choice on platforms like Amazon India, students often seek digital PDF versions for quick reference. Limited previews are available on Google Books. However, "exclusive" or full-text PDF downloads are typically restricted by copyright held by Krishna Prakashan Media. Institutional access through university libraries or legal digital repositories like Scribd is the recommended path for securing legitimate study materials. Topology Book 1-6 Unit | PDF - Scribd

Dr. S. Krishna (full name often listed as Sanjay Krishna) earned his Ph.D. in Mathematics from the Indian Institute of Technology (IIT) Kanpur, specializing in algebraic and geometric topology. After a post‑doctoral stint at the University of Cambridge, he joined the faculty of the Department of Mathematics at National Institute of Technology (NIT) Calicut, where he has been teaching and supervising research for over a decade. His research interests include:

Krishna’s teaching portfolio includes several graduate‑level courses on point‑set topology, homotopy theory, and topological data analysis (TDA). The book we discuss draws heavily on his lecture notes, refined through years of classroom feedback.
Krishna Publication’s topology books are tailored to Indian university syllabi—covering point-set topology, countability and separation axioms, compactness, connectedness, and basic algebraic topology (homotopy, fundamental group). This makes them highly sought after for B.Sc. (Mathematics Hons.), M.Sc., and competitive exams like NET, GATE, and NBHM.
