Lemma 29.36.19. Let
be a commutative diagram of morphisms of schemes. Assume that
f is surjective, and étale,
p is étale, and
q is locally of finite presentation1.
Then q is étale.
Lemma 29.36.19. Let
be a commutative diagram of morphisms of schemes. Assume that
f is surjective, and étale,
p is étale, and
q is locally of finite presentation1.
Then q is étale.
Proof. By Lemma 29.34.19 we see that q is smooth. Thus we only need to see that q has relative dimension 0. This follows from Lemma 29.28.2 and the fact that f and p have relative dimension 0. \square
