quintasymptotic sequences over an ideal and quintasymptotic cograde

چکیده
let $i$ denote an ideal of a noetherian ring $r$. the purpose of this article is to introduce the concepts of quintasymptotic sequences over $i$ and quintasymptotic cograde of $i$, and to show that they play a role analogous to quintessential sequences over $i$ and quintessential cograde of $i$. we show that, if $r$ is local, then the quintasymptotic cograde of $i$ is unambiguously defined and behaves well when passing to certain related local rings. also, we use this cograde to characterize two classes of local rings.

Quintasymptotic sequences over an ideal and quintasymptotic cograde
Let $I$ denote an ideal of a Noetherian ring $R$. The purpose of this article is to introduce the concepts of quintasymptotic sequences over $I$ and quintasymptotic cograde of $I$, and to show that they play a role analogous to quintessential sequences over $I$ and quintessential cograde of $I$. We show that, if $R$ is local, then the quintasymptotic cograde of $I$ is una...
متن کاملtλESSENTIAL PRIME DIVISORS AND SEQUENCES OVER AN IDEAL
All rings in this paper are assumed to be commutative with identity, and they will generally also be Noetherian. In several recent papers the asymptotic theory of ideals in Noetherian rings has been introduced and developed. In this new theory the roles played in the standard theory by associated primes, i?-sequences, classical grade, and Cohen-Macaulay rings are played by, respectively, asympt...
متن کاملCocycles and Mañe Sequences with an Application to Ideal Fluids
Exponential dichotomy of a strongly continuous cocycle Φ is proved to be equivalent to existence of a Mañe sequence either for Φ or for its adjoint. As a consequence we extend some of the classical results to general Banach bundles. The dynamical spectrum of a product of two cocycles, one of which is scalar, is investigated and applied to describe the essential spectrum of the Euler equation in...

متن کاملSpaces of Ideal Convergent Sequences
In the present paper, we introduce some sequence spaces using ideal convergence and Musielak-Orlicz function ℳ = (M(k)). We also examine some topological properties of the resulting sequence spaces.
متن کاملIdeal convergence of bounded sequences
We generalize the Bolzano-Weierstrass theorem (that every bounded sequence of reals admits a convergent subsequence) on ideal convergence. We show examples of ideals with and without the Bolzano-Weierstrass property, and give characterizations of BW property in terms of submeasures and extendability to a maximal P-ideal. We show applications to Rudin-Keisler and Rudin-Blass orderings of ideals ...
