Generalized Local Homology Modules of Complexes
The theory of local homology modules was initiated by Matlis in 1974. It is a dual version of the theory of local cohomology modules. Mohammadi and Divaani-Aazar (2012) studied the connection between local homology and Gorenstein flat modules by using ...

FINITENESS PROPERTIES OF FORMAL LOCAL HOMOLOGY MODULES [PDF]
Let (R, m) be a commutative Noetherian ring, a an ideal of R and M an Artinian R-module. In this paper, we investigate the structure of the formal local homology. We prove several results concerning finiteness properties of formal local homology module.

A REMARK ON THE COUNTABLY Σ−CS RING
Let 𝑅 be a ring such that 𝑅𝑅 = 𝑒1 𝑅 ⊕ · · · ⊕ 𝑒𝑛 𝑅, where each 𝑒𝑖 𝑅 is a uniform right ideal and {𝑒𝑖 | 1 ≤ 𝑖 ≤ 𝑛} is a set of idempotents. We consider the following condition on 𝑅𝑅 : for all 𝑖, 𝑗 ∈ {1, . . . , 𝑛}, the module 𝑒𝑖 𝑅 does not embed in any

ON VANISHING OF GENERALIZED LOCAL HOMOLOGY MODULES AND ITS DUALITY [PDF]
In this paper we study the vanishing and non-vanishing of generalized local cohomology and generalized local homology. In particular for a Noetherian local ring (R;m) and two non-zero finitely generated R-modules M and N, it is shown that H_m^{dimN} (M ...

Embedding Noetherian Rings in Artinian Rings
A well-known theorem of \textit{A. H. Schofield} [``Representation of rings over skew fields'', Lond. Math. Soc. Lect. Note Ser. 92, CUP, Cambridge (1985; Zbl 0571.16001)] asserts that an algebra \(A\) over a field can be embedded in a right Artinian ring if and only if there is a faithful Sylvester rank function on finitely presented \(A\)-modules.

Let S S be a subring of a ring R R such that R R is a finitely generated right S S -module. Clearly, if S S is a right Noetherian ring then so is R R

Polynomial Rings over Pseudovaluation Rings
Let R be a ring. Let σ be an automorphism of R. We define a σ-divided ring and prove the following. (1) Let R be a commutative pseudovaluation ring such that x∉P for any P∈Spec(R[x,σ]) . Then R[x,σ] is also a pseudovaluation ring.
