ON THE ASSOCIATED PRIME IDEALS OF LOCAL COHOMOLOGY MODULES DEFINED BY A PAIR OF IDEALS
Journal Title: Discussiones Mathematicae - General Algebra and Applications - Year 2016, Vol 36, Issue 1
Abstract
Let I and J be two ideals of a commutative Noetherian ring R and M be an R-module. For a non-negative integer n it is shown that, if the sets AssR(Extn R(R/I, M)) and SuppR(ExtiR(R/I, Hj I,J(M))) are finite for all i ≤ n + 1 and all j < n, then so is AssR(HomR(R/I, HnI,J(M))). We also study the finiteness of AssR(ExtiR(R/I, HnI,J (M))) for i = 1, 2.

COMPLICATED BE-ALGEBRAS AND CHARACTERIZATIONS OF IDEALS
In this paper, using the notion of upper sets, we introduced the notions of complicated BE-Algebras and gave some related properties on complicated, self-distributive and commutative BE-algebras. In a self-distributive a...
IF-FILTERS OF PSEUDO-BL-ALGEBRAS
Characterizations of IF-filters of a pseudo-BL-algebra are established. Some related properties are investigated. The notation of prime IF- filters and a characterization of a pseudo-BL-chain are given. Homomorphisms of...
GENERALIZED DERIVATIONS WITH LEFT ANNIHILATOR CONDITIONS IN PRIME AND SEMIPRIME RINGS
Let R be a prime ring with its Utumi ring of quotients U, C = Z(U) be the extended centroid of R, H and G two generalized derivations of R, L a noncentral Lie ideal of R, I a nonzero ideal of R. The left annihilator of S...
ON THE SECOND SPECTRUM OF LATTICE MODULES
The second spectrum Specs(M) is the collection of all second elements of M. In this paper, we study the topology on Specs(M), which is a generalization of the Zariski topology on the prime spectrum of lattice modules. Be...
Note on Ideal Based Zero-Divisor Graph of a Commutative Ring
In this paper, we consider the ideal based zero divisor graph I (R) of a commutative ring R. We discuss some graph theoretical properties of I (R) in relation with zero divisor graph. We also relate certain parameters...
