Information for students

Category theory is a relatively recent unifying theory for all of mathematics, which was founded in 1945 by Samuel Eilenberg and Saunders Mac Lane. In some sense, it gives a “new era” in mathematics, which follows the “set-theoretic era”. Category-theoretic ideas have been applied to geometry, algebra, and logic; new methods and applications are still being actively developed and investigated. Category theory has many applications also outside mathematics, particularly in computer science.

The most famous text on basic category theory is the following one:

S. Mac Lane, Categories for the Working Mathematician, Graduate Texts in Mathematics, Springer 1998 (2nd Ed)

Since an appreciation of category theory requires a relatively deep and broad knowledge of mathematics, usually students are introduced to it during their postgraduate studies. In South Africa, postgraduate study in category theory is offered by the University of Cape Town, and also other universities in South Africa, including Stellenbosch University.
