Abstract

Abstract: The purpose of this paper is to introduce two new classes of rings that is closely related to the classes of piecewise Noetherian domains and piecewise w -Noetherian domains. Let H = { R | R is a commutative ring and Nil ( R ) is a divided prime ideal of R } . Let R ∈ H be a ring with total quotient ring T ( R ), and set ϕ : T ( R ) → R Nil ( R ) such that ϕ ( a b ) = a b for every a ∈ R and every b ∈ R ∖ Z ( R ) . Then ϕ is a ring homomorphism from T ( R ) into R Nil ( R ), and ϕ restricted to R is also a ring homomorphism from R into R Nil ( R ) given by ϕ ( x ) = x 1 for every x ∈ R . At this setting, we introduce the notions of ϕ -piecewise Noetherian rings and ϕ -piecewise w -Noetherian rings and we show that the theories of ϕ -piecewise Noetherian (resp. ϕ -piecewise w -Noetherian) rings resemble those of piecewise Noetherian (resp. piecewise w -Noetherian) domains.
