## Introduction to Categories and Categorical Logic

Introduction to Categories and Categorical Logic by Samson Abramsky and Nikos Tzevelekos.

Category theory is important for theoretical CS and I suspect should skilled explanations come along, CS practice as well.

From the preface:

The aim of these notes is to provide a succinct, accessible introduction to some of the basic ideas of category theory and categorical logic. The notes are based on a lecture course given at Oxford over the past few years. They contain numerous exercises, and hopefully will prove useful for self-study by those seeking a first introduction to the subject, with fairly minimal prerequisites. The coverage is by no means comprehensive, but should provide a good basis for further study; a guide to further reading is included.

The main prerequisite is a basic familiarity with the elements of discrete mathematics: sets, relations and functions. An Appendix contains a summary of what we will need, and it may be useful to review this first. In addition, some prior exposure to abstract algebraâ€”vector spaces and linear maps, or groups and group homomorphismsâ€”would be helpful.

Under further reading, F. Lawvere and S. Schanuel, Conceptual Mathematics: A First Introduction to Categories, Cambridge University Press, 1997, is described by the authors as “idiosyncratic.” Perhaps so but I found it to be a useful introduction.
