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 to learn basic category theory and explore some important concrete toposes in a hands-on manner.
