Who needs category theory?

The goal of this note is to give a high-level explanation of that necessity of category theory, which avoids details and which suggests that the case of topological quantum computing is far from unique.

A Brisk Tour of (Enriched) Category Theory

In this paper, I will take you on a brief and brisk tour of the theory of (enriched) categories. While we won’t have time to see the theorems of category theory, we will see how the definitions unify

An Introduction to Category Theory

This book is an excellent introduction to all of the basics of category theory, and goes through the various associated gadgetry, such as functors, natural transformations, limits and colimits; and then explains adjunctions.

A General Framework for Representation

This chapter presents a general framework for representation based on category theory, setting the basis for a theory of mental representation, able to relate empirical findings, uniting them into a sound theoretical corpus.

Expansion in Lifts of Graphs

The central goal of this thesis is to better understand, and explicitly construct, expanding towers G1,G2, . . ., which are expander families with the additional constraint that Gn+1 is a lift of Gn

A taste of category theory for computer scientists

Category theory is a field that impinges more and more frequently on the awareness of many computer scientists, especially those with an interest in programming languages and formal specifications.

The Influence of M. H. Stone on the Origins of Category Theory

This talk is a small piece of historical investigation, intended to be an example of history in the retrospective sense: Starting with some currently active ideas in category theory, it will examine

Reflections on the Categorical Foundations of Mathematics

Most practicing mathematicians see no need for the foundations of their subject. But those who wish to place it on a solid ground usually pick set theory, an axiomatic treatment of the membership

Comments on the Development of Topos Theory

Summarizing several threads in the development of the Elementary Theory of Toposes in its first 30 years 1970-2000, this historical article prepares the reader for later publication such as
