	Complete space - Wikipedia, the free encyclopedia
		If this completion procedure is applied to a normed vector space, one obtains a Banach space containing the original space as a dense subspace, and if it is applied to an inner product space, one obtains a Hilbert space containing the original space as a dense subspace.
		Note that completeness is a property of the metric and not of the topology, meaning that a complete metric space can be homeomorphic to a non-complete one.
		Completely metrizable spaces can be characterized as those spaces which can be written as an intersection of countably many open subsets of some complete metric space.

		More technically, the reals are complete (in the sense of metric spaces or uniform spaces, which is a different sense than the Dedekind completeness of the order in the previous section).
		This sense of completeness is most closely related to the construction of the reals from Cauchy sequences (the construction carried out in full in this article), since it starts with an Archimedean field (the rationals) and forms the uniform completion of it in a standard way.
		By virtue of being a totally ordered set, they also carry an order topology; the topology arising from the metric and the one arising from the order are identical.

	Complete space (Site not responding. Last check: 2007-10-20)
		In mathematical analysis, a metric space M is said to be complete if every Cauchy sequence of points in M has a limit in M.
		By using different notions of distance on the rationals, one obtains different incomplete metric spaces whose completions are the p-adic numberss.
		It is also possible to define the concept of completeness for uniform spaces using Cauchy netss instead of Cauchy sequences.

		For instance, the rational numbers are not complete, because √2 is "missing".
		Cantor's contsruction of the real numbers is a special case of this; the real numbers are the completion of the rational numbers using the ordinary absolute value to measure distances.

		More technically, the reals are complete (in the sense of metric space s or uniform space s, which is a different sense than the Dedekind completeness of the order in the previous section).
		This sense of completeness is most closely related to the construction of the reals from surreal number s, since that construction starts with a proper class that contains every ordered field (the surreals) and then selects from it the largest Archimedean subfield.
		By virtue of being a totally ordered set, they also carry an order topology ; the topology arising from the metric and the one arising from the order are identical.

		(We refer to the notion of completeness in uniform spaces rather than the related and better known notion for metric spaces, since the definition of metric space relies on already having a characterisation of the real numbers.)
		It is not true that R is the only uniformly complete ordered field, but it is the only uniformly complete Archimedean field, and indeed one often hears the phrase "complete Archimedean field" instead of "complete ordered field".
		Occasionally, formal elements +∞ and -∞ are added to the reals to form the extended real number line, a compact space which is not a field but retains many of the properties of the real numbers.

	Cauchy sequence - Wikipedia, the free encyclopedia - TESTVERSION (Site not responding. Last check: 2007-10-20)
		The real numbers are complete, and the standard construction of the real numbers involves Cauchy sequences of rational numbers.
		The rational numbers themselves are not complete: for example the following sequence of rational numbers has the irrational square root of two as its limit (each numerator is the square of the previous numerator plus twice the square of the previous denominator, while each denominator is twice the product of the previous numerator and denominator).
		If the topology of X is compatible with a translation-invariant metric d, the two definitions agree.

		Typically, an AS-level topology estimate is derived from BGP routing tables.
		One fundamental trade-off in collecting AS-level topology is ``completeness'' vs. ``freshness.'' By using routing registry data and accumulating topology over time, some out-dated information may be introduced into the topology.
		By including auxiliary information with the topology, users have the flexibility to decide which sources of information they consider to be valid and determine how ``fresh'' the topology should be.

	Uniform space : Entourage (topology) (Site not responding. Last check: 2007-10-20)
		In topology, one defines uniform spaces in order to study concepts such as uniform continuity, completeness and uniform convergence.
		Every metric space (M, d) can be considered as a uniform space by defining a subset V of M × M to be an entourage if and only if there exists an ε > 0 such that for all x, y in M with d(x, y) < ε we have (x, y) in V.
		Every uniform space is a completely regular topological space, and conversely, every completely regular space can be turned into a uniform space (often in many ways) so that the induced topology coincides with the given one.

		The conjecture then asserts that near the standard conformal structure on $S^3$ (in an appropriate sense) the moduli spaces of positive and negative frequency subspaces are transverse (i.e., their tangent spaces at the standard conformal structure give a direct sum decomposition).
		In spite of this work (and in contrast to the case of $\SU(2)$ symmetry, where Hitchin provides a classification) the issue of completeness for negative SDE Hermitian metrics is not yet fully explored, and for the toric SDE metrics in general, the complete examples are far from understood.
		In \cite{CaSi:emcs}, Calderbank and M. Singer constructed examples of complete SDE metrics on resolutions of complex cyclic singularities and showed that the moduli of such metrics is (continuously) infinite dimensional.
