$1\frac12$ and $2$ generator ideals in Prüfer domains1
An K-module M is generated by VA elements if M can be generated by two elements, the first of which can be an arbitrarily specified element of M -(rad R)M.This last restriction is natural because, by Nakayama's Lemma, elements of (rad R)M can always be omitted from finite generating sets.If …
