Lemma 29.47.10. Let $X$ be a scheme. The following are equivalent

$X$ is absolutely weakly normal,

$X$ is equal to its own absolute weak normalization, i.e., the morphism $X^{awn} \to X$ is an isomorphism,

if $\pi : Y \to X$ is a universal homeomorphism with $Y$ reduced, then $\pi $ is an isomorphism.
