The notion of a topos (a.k.a. elementary topos) is a fundamental concept of category theory. A topos is a category that shares several properties with the category of sets. Toposes appear in many areas of mathematics, for example geometry, topology, combinatorics, and logic. This project is an opportunity for students to learn basic category theory and explore, in a hands-on manner, some important concrete toposes and related categories that arise in graph theory.
