74.18 Properties of morphisms local in the smooth topology on the source

Here are some properties of morphisms that are smooth local on the source.

Lemma 74.18.1. The property $\mathcal{P}(f)=$“$f$ is smooth” is smooth local on the source.

Proof. Follows from Lemma 74.14.3 using Morphisms of Spaces, Definition 67.37.1 and Descent, Lemma 35.30.1. $\square$
