Local and Global Tameness in Krull Monoids
Local and Global Tameness in Krull Monoids
Let H be a Krull monoid with finite class group G such that every class contains a prime divisor. Then the global tame degree equals zero if and only if H is factorial (equivalently, |G| = 1). If |G| > 1, then , where is the Davenport constant of G. …
