Uniqueness and $(\infty,2)$-Naturality of Yoneda

Category Theory 2025-08-27 v2 Algebraic Topology

Abstract

We show that the Yoneda embedding extends to an (,2)(\infty,2)-natural transformation. Furthermore, as such, it is uniquely determined by its value at the trivial \infty-category. We also study the naturality of the Yoneda lemma in its arguments, showing that it is an isomorphism of (,2)(\infty,2)-natural transformations.
