This concise, original text for a one-semester course on the subject is derived from courses that author Emily Riehl taught at Harvard and Johns Hopkins Universities. The treatment introduces the essential concepts of category theory: categories, functors, natural transformations, the Yoneda lemma, limits and colimits, adjunctions, monads, and other topics. Suitable for advanced undergraduates and graduate students in mathematics, the text provides tools for understanding and attacking difficult problems in algebra, number theory, algebraic geometry, and algebraic topology. Drawing upon a broad range of mathematical examples from the categorical perspective, the author illustrates how the concepts and constructions of category theory arise from and illuminate more basic mathematical ideas. Prerequisites are limited to familiarity with some basic set theory and logic. Review: Excelente libro - Muy buen libro para profundizar en teoría de categorías, aunque no lo recomendaría para un primer contacto con la materia (Awodey es un buen comienzo). Si bien la impresión no es de buena calidad (bajo gramaje de las hojas), no se puede pedir más por un precio tan bajo. También es de destacar que la autora haya tenido la gentileza de dejar disponible el pdf gratis para descargar desde su página web.

Livro de capa comum, excelente impressão, porém letras são pequenas. ### ⭐⭐⭐⭐⭐ Excellent but very challenging for the beginner *by K***H on 31 August 2020* I returned to this book after some time passed and I appreciate it more. First of all, it wasn't all that hard to eventually fill in the gaps and be able to use the book. Second, ChatGPT and other LLMs are now available for interactively filling in gaps, and self-contained introductions seem less important now than they did a few years ago. After getting past my initial difficulties, I can also appreciate that the author's contextualization of the material with quotations, hints, and footnotes and the choice of references is very well considered and useful. This is how I felt initially (original review, 4 stars): I'm using this book for self-study and started out reading and working problems as I went along. It didn't work: the book is too difficult as a first text for this purpose. I do think this is a good book, but it's too advanced for a first introduction. There are some statements in the introduction to the effect that few prerequisites are required if you also have some "mathematical maturity". Don't be fooled: this is code for already knowing category theory, and some essential definitions are missing. I recommend that if you are acquiring category theory by self-study you should start with "Category Theory for the Working Mathematician," because that book does define everything with complete clarity. And don't let the title of that book scare you: it is perfectly sufficient for the beginner. Steve Awodey's book "Category Theory" is another good starting point or second reference. Essentially this is the problem: to understand basic category theory you need an unambiguous interpretations of commutative and non-commutative diagrams, abstract categories ("metacategories"), and concrete categories. Then as each auxiliary definition and tool is built up you need to understand its construction unambiguously and in its full generality. These things are all fairly simple. I'm observing that once people understand all of these things together as a "language" they enjoy the experience so much that they immediately forget how to explain the basic definitions to their readers and want to just write category theory at you. And to some extent that is a positive and promising thing. I'm hoping that once I get my basic grounding in category theory and come back to finish reading this book that the more advanced material is presented well enough that I can understand it. I expect that that will be true based on reviews by more advanced readers. ## Frequently Bought Together - Category Theory in Context (Aurora: Dover Modern Math Originals) - Topoi: The Categorial Analysis of Logic (Dover Books on Mathematics) - An Invitation to Applied Category Theory: Seven Sketches in Compositionality --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/88762148-category-theory-in-context-aurora-dover-modern-math-originals](https://www.desertcart.us/products/88762148-category-theory-in-context-aurora-dover-modern-math-originals) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-13*
