Coprime packedness and set theoretic complete intersections of ideals in polynomial rings

Coprime packedness and set theoretic complete intersections of ideals in polynomial rings

A ring $R$ is said to be coprimely packed if whenever $I$ is an ideal of $R$ and $S$ is a set of maximal ideals of $R$ with $I\subseteq \bigcup \{M\in S\}$, then $I\subseteq M$ for some $M\in S$. Let $R$ be a ring and $R\langle X\rangle$ be the localization …
