基础范畴论

Basic Category Theory

Tom Leinster

AI总结:

本教材面向数学背景薄弱的读者,以泛性质为核心,通过伴随函子、可表函子和极限三种方式阐述该概念,结合大量例子与细致解释,帮助理解范畴论基础。

摘要:

这本简短的范畴论入门教材面向数学背景相对薄弱的读者(例如本科数学学位的前半段)。其核心是贯穿数学领域的重要概念——泛性质。在介绍基本定义的章节之后,独立章节分别通过伴随函子、可表函子和极限三种方式阐述泛性质,最后一章将三者结合。对于每个新的范畴概念,均提供大量来自数学不同分支的例子;在抽象性跳跃特别大的地方(如米田引理),读者将看到细致且详尽的解释。

英文摘要:

This short introductory category theory textbook is for readers with relatively little mathematical background (e.g. the first half of an undergraduate mathematics degree). At its heart is the concept of a universal property, important throughout mathematics. After a chapter introducing the basic definitions, separate chapters present three ways of expressing universal properties: via adjoint functors, representable functors, and limits. A final chapter ties the three together. For each new categorical concept, a generous supply of examples is provided, taken from different parts of mathematics. At points where the leap in abstraction is particularly great (such as the Yoneda lemma), the reader will find careful and extensive explanations.
