Basic Category Theory


Basic Category Theory is an introductory category theory textbook. Features:
  • It doesn't assume much, either in terms of background or mathematical maturity.
  • It sticks to the basics.
  • It's short.
Advanced topics are omitted, leaving more space for careful explanations of the core concepts. I have used versions of this text to teach final-year undergraduate and master's-level courses at the Universities of Glasgow and Edinburgh.
