摘要:
Given (T,S,R), a Torsion-Torsion Free (T.T.F) theory in an abeiian category A with sufficient projective and injective objects. it is shown that the intersection of the full subcategories T and R is the additive category of fractions with respect to the Serre subcategory S, R ⋂ T is an abelian category. An equivalence is established between the subcategories of the projective objects of R ⋂ T and the projective objects of A in T. There is also a similar equivalence for injective objects. If T has a generating set of small projective objects, it is shown that R has a cogenerating set of indecomposable injectives.

摘要:
An R-module M is said to be bounded if for any essential sub-module N of M, there exists an ideal K of R with K/ann(M) essential as a right ideal in R/ann(M) such that MK ⊆ N, The purpose of this paper is to provide conditions on a bounded module M that determine when R/ann(M) is right FBN.

摘要:
Let A be a Mori domain; is it true that A[[XJ] is also a Mori domain? I give several instances where the answer is positive, even though I conjecture that there is a Mori domain A such that A[[X1] is not a Mori domain.
