Chain conditions on composite Hurwitz series rings

open access: yesOpen Mathematics, 2017
In this paper, we study chain conditions on composite Hurwitz series rings and composite Hurwitz polynomial rings. More precisely, we characterize when composite Hurwitz series rings and composite Hurwitz polynomial rings are Noetherian, S-Noetherian or ...

A note on the countable union of prime submodules

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 10, Page 641-643, 2001., 2001
Let M be a finitely‐generated module over a Noetherian ring R. Suppose 𝔞 is an ideal of R and let N = 𝔞M and 𝔟 = Ann(M/N). If 𝔟⫅J(R), M is complete with respect to the 𝔟‐adic topology, {Pi} i≥1 is a countable family of prime submodules of M, and x ∈ M, then x + N⫅∪i≥1Pi implies that x + N⫅Pj for some i ≥ 1.

Universally catenarian domains of D + M type, II

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 14, Issue 2, Page 209-214, 1991., 1991
Let T be a domain of the form K + M, where K is a field and M is a maximal ideal of T. Let D be a subring of K such that R = D + M is universally catenarian. Then D is universally catenarian and K is algebraic over k, the quotient field of D. If [K : k] < ∞, then T is universally catenarian.

On the annihilators and attached primes of top local cohomology modules [PDF]

open access: yes, 2014
Let \frak a be an ideal of a commutative Noetherian ring R and M a finitely generated R-module. It is shown that {\rm Ann}_R(H_{\frak a}^{{\dim M}({\frak a}, M)}(M))= {\rm Ann}_R(M/T_R({\frak a}, M)), where T_R({\frak a}, M) is the largest submodule of M

Socle finiteness of local cohomology modules and Gorenstein ideals

open access: yes, 2013
The purpose of this paper is to give some equivalent conditions to the socle and Bass numbers' conjectures which raised by C. Huneke in (Problems on local cohomology, Free resolutions in commutative algebra and algebraic geometry, Res. Notes Math.

Weak dimension of FP-injective modules over chain rings

open access: yes, 2015
It is proven that the weak dimension of each FP-injective module over a chain ring which is either Archimedean or not semicoherent is less or equal to ...

Noetherian rings of composite generalized power series

open access: yesOpen Mathematics
Let A⊆BA\subseteq B be an extension of commutative rings with identity, (S,≤)\left(S,\le ) a nonzero strictly ordered monoid, and S*=S\{0}{S}^{* }\left=S\backslash \left\{0\right\}.

Topological Noetherianity of the infinite half-spin representations

open access: yesForum of Mathematics, Sigma
We prove that the infinite half-spin representations are topologically Noetherian with respect to the infinite spin group. As a consequence, we obtain that half-spin varieties, which we introduce, are defined by the pullback of equations at a finite ...

Analysis of the immunomodulatory properties of mycobacterium cell wall fraction on the cytokine production of peripheral blood mononuclear cells of healthy dogs

open access: yesVeterinary Dermatology, Volume 35, Issue 6, Page 595-604, December 2024.
Background – Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode‐of‐action requires further research. Objective – To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme‐linked ...

The space of finitely generated rings

open access: yes, 2009
The space of marked commutative rings on n given generators is a compact metrizable space. We compute the Cantor-Bendixson rank of any member of this space.
