Minimal relations and catenary degrees in Krull monoids
Minimal relations and catenary degrees in Krull monoids
Let $H$ be a Krull monoid with class group $G$. Then, $H$ is factorial if and only if $G$ is trivial. Sets of lengths and sets of catenary degrees are well studied invariants describing the arithmetic of $H$ in the non-factorial case. In this note, we focus on the set …
