Abstract

For a proper submodule NN of a finitely generated module MM over a Noetherian ring, the product of prime ideals which occur in a regular prime extension filtration of MM over NN is defined as its generalized prime ideal factorization in MM. In this article, we find conditions for a product of prime ideals to be the generalized prime ideal factorization of a submodule of some module. We show that a power of a prime ideal occurs in a generalized prime ideal factorization only if it is not equal to its lesser powers. Also, we show that p1r1pnrn{{\mathfrak{p}}_1}^{r_1} \cdots {{\mathfrak{p}}_{n}}^{r_{n}} is a generalized prime ideal factorization if and only if for each 1in1 \leq i \leq n, piri{{\mathfrak{p}}_i}^{r_i} is the generalized prime ideal factorization of some submodule of a module.
