Definition 29.47.1. Let $A$ be a ring.

1. We say $A$ is seminormal if for all $x, y \in A$ with $x^3 = y^2$ there is a unique $a \in A$ with $x = a^2$ and $y = a^3$.

2. We say $A$ is absolutely weakly normal if (a) $A$ is seminormal and (b) for any prime number $p$ and $x, y \in A$ with $p^ px = y^ p$ there is a unique $a \in A$ with $x = a^ p$ and $y = pa$.
