Lemma 10.105.8. Let $R$ be a Noetherian ring.

1. $R$ is catenary if and only if $R/\mathfrak p$ is catenary for every minimal prime $\mathfrak p$.

2. $R$ is universally catenary if and only if $R/\mathfrak p$ is universally catenary for every minimal prime $\mathfrak p$.

Proof. If $\mathfrak a \subset \mathfrak b$ is an inclusion of primes of $R$, then we can find a minimal prime $\mathfrak p \subset \mathfrak a$ and the first assertion is clear. We omit the proof of the second. $\square$
