Abstract
In the first section of this paper the authors give some classes of modules where the two concepts π and prime are equivalent. Also, they provide conditions under which a given ring R is a Dedekind domain if and only if the R-module M is prime. In the final section they answer a question concerning modules which satisfy the radical formula.
