Topic: Descending chain condition


  
  Ascending chain condition - Wikipedia, the free encyclopedia
The ascending chain condition on P is equivalent to the maximum condition: every nonempty subset of P has a maximal element.
Similarly, the descending chain condition is equivalent to the minimum condition: every nonempty subset of P has a minimal element.
A totally ordered set that satisfies the descending chain condition is called a well-ordered set.

 Artinian - Wikipedia, the free encyclopedia
In mathematics, Artinian is an adjective that describes objects that satisfy particular cases of the descending chain condition.
A ring is an Artinian ring if it satisfies the descending chain condition on ideals.
The concept is named for Emil Artin, who classified all simple rings whose one-sided ideals satisfy the descending chain condition.

He waited on the landing watching the steps of the escalators slowly descend toward him and, at the end of their journey, telescope in upon themselves and disappear.
It was, of course, possible that he had to descend two flights of stairs for every floor of the department store.
Because he was hungry and because he was tired and because the futility of mounting endless flights of descending escalators was, as he now considered it, a labor of Sisyphus, he returned, descended, gave in.

Since the descending chain condition treats all left ideals the hypothesis of this theorem is phrased in second order rather than first order logic.
The fact that a polynomial ring over a field is Noetherian yields to a descending chain condition on closed subgroups.
Both proofs use the chain conditions and induction on rank as a substitute for cardinality.

 Finite Rings   (Site not responding. Last check: 2007-10-08)
It is clear that such a ring satisfies the descending chain condition for ideals.
The ring also satisfies the ascending chain condition; any ascending chain of ideals is constant after a finite stage.
The given condition on f can be restated by saying that H(f) is a unit in the ring of formal power series and L(f) is in M[X] where M is the maximal ideal of the ring A.

Hence the family (Zt)t2N is descending M = Z0 ' Z1 ' : : : ' Zt ' : : : and it is stationary at some t0, that is, Zt0 = Zt0+1 = : : :.
Hence a descending family of algebraic subsets of X is stationary.
The assumptions of Theorem 4.2 are satisfied as any descending family of algebraic sets is stationary, and under the assumptions of this corollary the sets considered in Definition 4.1 are algebraic as they can be expressed in terms of vanishing principal minors of algebraic functions.

 Chains of Modules   (Site not responding. Last check: 2007-10-08)
If you like set theory, think of a chain as a map from the ordinals into the submodules of m, where the submodules increase or decrease as the ordinals advance.
At approximately the same time, Artin (biography) explored modules with no infinite descending chains, and these modules are now called artinian.
Another synonym for noetherian is "ascending chain condition", or ACC.

It is shown that under certain general conditions each of these operations may be defined in terms of the other.
It is shown that each element of a modular lattice in which suitable chain conditions hold, may be represented as a product of irreducibles; and if there are two such decompositions, the number of irreducibles is the same and they are similar in pairs.
In the first part the structure of ideal lattices in the vicinity of the unit element is characterized in terms of arithmetical and semi-arithmetical lattices.

One property people often ask as a first question about a ring is what are some basic properties of its ideals.
One property that turns out to be quite useful in proving many basic results about a ring is contained in information concerning chains of ideals.
Two seemingly dueling notions are the ascending chain condition (ACC) and the descending chain condition (DCC).

In this paper, causal rational encoders over commutative rings are considered and a general criterion of Johannesson and Wan (see IEEE Trans.
Theory, vol.39, p.1219-33, July 1993) is generalized to rings, which satisfy the descending chain condition.
Moreover, a new simple test is presented that reduces the minimality question from the ring to the field case.

 Fitting ideals for finitely presented algebraic dynamical systems   (Site not responding. Last check: 2007-10-08)
We consider a class of algebraic dynamical systems introduced by Kitchens and Schmidt.
Under a weak finiteness condition - the Descending Chain Condition - the dual modules have finite resentations.
Using methods from commutative algebra we show how the dynamical properties of the system may be deduced from the Fitting ideals of a finite free resolution of the finitely presented module.
