Abstract : A commutative ring with unity R is called EM-Hermite if for each a,b∈R there exist c,d,f∈R such that a=cd,b=cf and the ideal (d,f) is regular in R. We showed in this article that R is a PP-ring if and only if the idealization R(+)R is an EM-Hermite ring if and only if R[x]/(xⁿ⁺¹) is an EM-Hermite ring for each n∈ℕ.
We generalise some results, and answer some questions in the literature.
