A quiz on natural transformations and related concepts in category theory, including functors, isomorphisms, and extensions

This quiz covers the fundamental concepts and principles of Category Theory and Topology, including categories, functors, natural transformations, topological spaces, and continuous maps.

Yoneda's Lemma is a fundamental result in category theory stating that for any locally small category C, object A in C, and functor F: C → Set, there is a natural isomorphism Nat(Hom(A, -), F) ≅ F(A). This lemma reveals deep connections between objects and their representable functors, and is essential for understanding representability, presheaves, and adjunctions.
