👉 A topos is a mathematical structure that generalizes the concept of a category. It is a type of structured space or set, where the objects are sets and morphisms are functions between these sets. Toposes have many applications in mathematics, including algebraic topology, category theory, and computer science. In a topological space, two points can be considered to be equivalent if they have the same distance from each other. Similarly, in a topological space, two sets can be considered to be
