Abstract nonsense is a popular term used by mathematicians to describe certain kinds of arguments and concepts in category theory. This term is believed to have been coined by the mathematician Norman Steenrod, one of the developers of the categorical point of view. Like all branches of mathematics, category theory has its own special vo-cabulary, which we will meet as we go along. But since the idea of universal property is so important, I will use this introduction to explain it with no jargon at all, by means of examples. Our ﬁrst example of a universal property is very simple. Category theory has itself grown to a branch in mathematics, like algebra and analysis, that is studied like any other one. One should not confuse the potential bene ts that category theory may have (for the theory underlying algorithmics, say) with the di culty and complexity, and fun, of doing category theory as a specialisation in itself. Abstract: This short introduction to category theory is for readers with relatively little mathematical background. At its heart is the concept of a universal property, important throughout mathematics. Barr and Wells, in addition to Toposes, Triples and Theories, have written Category Theory for the Computing Sciences, a comprehensive tome which goes through most of the interesting aspects of category theory with a constant explicit drive to relate everything to computer science whenever possible. Both books are available online as TAC Reprints. course in category theory. Although heavily based on Mac Lane’s Categories for the Working Mathematician, the course was designed to be self-contained, drawing most of the examples from category theory itself. The course was intended for post-graduate students in theoretical computer science at the. Introduction. This Wikibook is an introduction to category theory. It is written for those who have some understanding of one or more branches of abstract mathematics, such as group theory, analysis or topology. The book contains many examples drawn from various branches of math. The language of category theory has been used to formalize concepts of other high-level abstractions such as sets, rings, and groups. Informally, category theory is a general theory of functions. Several terms used in category theory, including the term "morphism", are used differently from their uses in the rest of mathematics. Some reviews indicate this book is an "easy" introduction to category theory (CT)--and it is well written--but that's not its primary virtue. It is something even better: Simmons has the knack for writing concretely about an inherently abstract topic. Lectures on elementary category theory: part 1. Household sharing included.
