Topic: Bounded complete


  
  Bounded complete - Wikipedia, the free encyclopedia
Bounded completeness then yields the existence of a least upper bound of any "consistent" subset, which can be regarded as the most general piece of information that captures all the knowledge present within this subset.
Bounded completeness has various relationships to other completeness properties, which are detailed in the article on completeness in order theory.
Hence it is important to distinguish between a bounded complete poset and a bounded cpo.

 Completeness (order theory)   (Site not responding. Last check: 2007-11-07)
All completeness properties are described along a similar scheme: one describes a certain class of subsets of a partial order that are required to have a supremum or infimum.
Although concepts with the names "complete" and "bounded" were already defined, confusion is unlikely to occur since one would rarely speak of a "bounded complete poset" when meaning a "bounded cpo" (which is just a "cpo with greatest element").
Consequently, bounded completeness is equivalent to the existence of all non-empty lower bounded infima.

 Complete partial order - Wikipedia, the free encyclopedia
A complete partial order (cpo) is a dcpo with a least element.
For instance, theorems involving directed completeness (and characterizations thereof) are to be found in the articles on continuous posets, algebraic posets, and the Scott topology.
All complete lattices are of course also directed complete and thus provide numerous (though not particularly instructive) examples for dcpos.

 Completeness - Wikipedia, the free encyclopedia
It should be noted that "complete" here is just a term that takes on specific meanings in specific situations, and not every situation in which a type of "completion" occurs is called a "completion".
Furthermore, an ordered field is complete if every non-empty subset of it that has an upper bound within the field has a least upper bound within the field, which should be compared to the (slightly different) order-theoretical notion of bounded completeness.
In computational complexity theory, a problem P is complete for a complexity class C, under a given type of reduction, if P is in C, and every problem in C reduces to P using that reduction.

 Scott domain - Wikipedia, the free encyclopedia
Since the empty set certainly has some upper bound, we can conclude the existence of a least element (the supremum of the empty set) from bounded completeness.
Also note that, while the term "Scott domain" is widely used with this definition, the term "domain" does not have such a general meaning: it may be used to refer to many structures in domain theory and is usually explained before it is used.
It should be remarked that the property of being bounded complete is equivalent to the existence of all non-empty infima.

 Complete Heyting algebra -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-11-07)
This article give various characterizations for the notion of a complete Heyting algebra and explains in which sense the notions of a complete Heyting algebra, a locale and a frame differ, although they describe the same mathematical objects.
Thus, a homomorphism of complete Heyting algebras is a morphism of frames that in addition preserves implication.
Usually the different names for complete Heyting algebras are employed to distinguish these three notions of a morphism implicitly.

 Metric space - Wikipedia, the free encyclopedia
If M is a connected Riemannian manifold, then we can turn M into a metric space by defining the distance of two points as the infimum of the lengths of the paths (continuously differentiable curves) connecting them.
We call such a subset complete, bounded, totally bounded or compact if it, considered as a metric space, has the corresponding property.
A simple way to construct a function separating a point from a closed set (as required for a completely regular space) is to consider the distance between the point and the set.

In domain theory, a subset S of a cpo X is bounded if there exists x in X such that for all s in S, s <= x.
In other words, there is some element above all of S. If every bounded subset of X has a least upper bound then X is boundedly complete.

 Completeness Order Theory   (Site not responding. Last check: 2007-11-07)
For this reason, posets with certain completeness properties can often be described as algebraic structures of a certain kind.
It turns out that in many cases it is possible to characterize completeness solely by considering appropriate algebraic structures in the sense of universal algebra, which are equipped with operations like
The considerations in this section suggest a reformulation of (parts of) order theory in terms of category theory, where properties are usually expressed by referring to the relationsships (morphisms, more specifically: adjunctions) between objects, instead of considering their internal structure.

 Completeness (order theory) - InformationBlast
The motivation for considering completeness properties derives from the great importance of suprema (least upper bounds, joins, "v") and infima (greatest lower bounds, meets, "^") to the theory of partial orders.
The posets with this property are the complete lattices.
Consequently, bounded completeness is equivalent to the existence of all non-empty infima.

For instance, the completion of a metric space M involves an isometry from M into M', a quotient of the space Cauchy sequences on M.
The original space M is thus isometrically isomorphic to a subspace of a complete metric space, and it is usually identified with this subspace.
Other embedding constructions show that every metric space is isometrically isomorphic to a closed subset of some normed vector space and that every complete metric space is isometrically isomorphic to a closed subset of some Banach space.

In mathematics, especially in order theory, the greatest element of a subset S of a partially ordered set is an element of S which is greater than or equal to any other element of S. The term least element is defined dually.
In the mathematical area of order theory, every partially ordered set P gives rise to a dual (or opposite) partially ordered set which is often denoted by Pop.
This is a glossary of some terms used in various branches of mathematics that are related to the fields of order, lattice, and domain theory.

Thanks for enlightening me. Keep in mind that "bounded" only makes sense in a metric space, and that "closed" implies X is a subset of something else (evey topological space is closed in itself).

A metric d on M is called intrinsic if any two points x and y in M can be joint by a curve with length arbitrarily close to d(x, y).
A metric space M is called bounded if there exists some number r > 0 such that d(x,y) ≤ r for all x and y in M (not to be confused with "finite", which refers to the number of elements, not to how far the set extends; finiteness implies boundedness, but not conversely).

If X is not totally bounded, there is some e>0 such that no finite collection of balls of radius e covers X. So I can pick x1 in X, x2 in X-B(x1,e), x3 in X - B(x1,e) - B(x2,e), and so on.
In somewhat fancier language, call a metric space \emph{totally bounded} if for every given real number $\varepsilon > 0$ it has a finite covering by $\varepsilon$-balls; then, as is easily seen, it is precompact if and only if it is totally bounded.
According to the standard characterization of compactness stated above $X$ cannot be totally bounded since it is assumed to be noncompact.
