# Topic: Regular space

###### In the News (Tue 21 May 13)

 Tychonoff space - Wikipedia, the free encyclopedia X is a completely regular space iff, given any closed set F and any point x that does not belong to F, there is a continuous function f from X to the real line R such that f(x) is 0 and f(y) is 1 for every y in F. Tychonoff spaces are precisely those topological spaces which can be embedded in a compact Hausdorff space. It is characterised by the universal property that, given a continuous map f from X to any other compact Hausdorff space Y, there is a unique continuous map g from βX to Y that extends f in the sense that f is the composition of g and j. en.wikipedia.org /wiki/Tychonoff_space   (600 words)

 Regular space - Wikipedia, the free encyclopedia X is a regular space iff, given any closed set F and any point x that does not belong to F, there exists a neighbourhood U of x and a neighbourhood V of F that are disjoint. (Hausdorffness); all are equivalent in the context of regular spaces. On the other hand, spaces that are regular but not completely regular, or preregular but not regular, are usually constructed only to provide counterexamples to conjectures, showing the boundaries of possible theorems. en.wikipedia.org /wiki/Regular_space   (942 words)

 Regular article - Regular military militia reserve 101st Airborne Division Mathematical - What-Means.com   (Site not responding. Last check: 2007-11-07) In the military, a regular unit is a military unit that is part of the regular forces (not militia or reserve). In graph theory, a regular graph is a graph such that the all the degrees of the vertices are equal. In topology, a regular space is one in which points are closed and any point can be separated from any closed set by open sets. www.what-means.com /encyclopedia/Regular   (231 words)

 Regular space   (Site not responding. Last check: 2007-11-07) X is a regular space iff, given any closed set F and any point x that does not belong to F, there are a neighbourhood U of x and a neighbourhood V of F that are disjoint. Taking the interiorss of these closed neighbourhoods, we see that the regular open sets form a base for the open sets of the regular space X. Suppose that A is a set in a topological space X and f is a continuous function from A to a regular space Y. www.sciencedaily.com /encyclopedia/regular_space   (981 words)

 Encyclopedia article on Topological space [EncycloZine]   (Site not responding. Last check: 2007-11-07) A linear graph is a topological space that generalises many of the geometric aspects of graphs with vertices and edges. A space is regular if whenever C is a closed set and p is a point not in C, then C and p have disjoint neighbourhoods. A space is completely regular if whenever C is a closed set and p is a point not in C, then C and {p} are functionally separated. encyclozine.com /Topological_space   (2350 words)

It may seem unnaturally restrictive to require that a regular function always extend to the ambient space, but it is very similar to the situation in a normal Just as with the regular functions on affine space, the regular functions on V form a ring, which we denote by k[V]. en-cyclopedia.com /wiki/Algebraic_geometry   (1655 words)

 Character design standards - Space Characters The no-break space is the same as the word space character with the added functionality of providing a way to prevent two words from being separated by a line break. The no-break space is not the same character as the figure space. The majority of these characters are traditional typographic space values or characters that are related to other character's width criteria. www.microsoft.com /typography/developers/fdsspec/spaces.htm   (894 words)

 Macromedia - ColdFusion LiveDocs : Regular expression syntax   (Site not responding. Last check: 2007-11-07) The pattern within the square brackets of a regular expression defines a character set that is used to match a single character. The regular expression [A-Z][a-z]* matches any word that starts with an uppercase letter and is followed by zero or more lowercase letters. The regular expression "[0-9]{3,}" specifies to match any integer number containing three or more digits: "123", "45678", etc. However, this regular expression does not match a one-digit or two-digit number. livedocs.macromedia.com /coldfusion/6/Developing_ColdFusion_MX_Applications_with_CFML/regexp3.htm   (2452 words)

 Normal space : Normal regular space   (Site not responding. Last check: 2007-11-07) X is a completely normal space if every subspace of X is normal. X is a perfectly normal space if every two disjoint closed sets can be precisely separated by a function. That is, given disjoint closed sets E and F, there is a continuous function f from X to the real line R such the preimages of {0} and {1} under f are E and F respectively. www.eurofreehost.com /no/Normal_regular_space_2.html   (353 words)

 Algebraic geometry - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-11-07) In classical algebraic geometry, the main objects of interest are the vanishing sets of collections of polynomials, meaning the set of all points that simultaneously satisfy one or more polynomial equations. Just as continuous functions are the natural maps on topological spaces and smooth functions are the natural maps on differentiable manifolds, there is a natural class of functions on an algebraic set, called regular functions. It may seem unnaturally restrictive to require that a regular function always extend to the ambient space, but it is very similar to the situation in a normal topological space, where the Tietze extension theorem guarantees that a continuous function on a closed subset always extends to the ambient topological space. xahlee.org /_p/wiki/Algebraic_geometry.html   (1675 words)

 [No title] Some time ago I had asked about polyhedra that tile space and got this response: ----------------------- Hop David observes that Euclidean 3-space can be monohedrally tiled with cubes, rhombic dodecahedra, truncated octahedra, triangular prisms, and hexagonal prisms and asks whether there are others. Leaving aside the tiling by rhombic dodecahedra, which is the dual of a uniform tiling by regular tetrahedra and octahedra, there are just five uniform monohedral tilings of Euclidean 3-space. These are the regular tiling {4, 3, 4}, with cubic cells; the "bitruncated" {4, 3, 4}, with truncated octahedral cells; the dual tilings {3, 6} x {oo} and {6, 3} x {oo}, with triangular or hexagonal prismatic cells; and one other tiling, by triangular prisms arranged in a different way. www.math.niu.edu /~rusin/known-math/01_incoming/fillspace   (674 words)

 Beiträge zur Algebra und Geometrie/Contributions to Algebra and Geometry, Vol. 39, No. 2, pp. 497--516, 1998   (Site not responding. Last check: 2007-11-07) Abstract: Considering the regular dodecahedron tilings in the spaces of constant curvature we look for the fixed point free discrete transformation groups that act simply transitively on the tiles. Because of the large number of cases we modify the general algorithm and apply it for finding all the non-equivariant face identifications of a regular polyhedron, and for choosing those ones that generate fixed point free groups, if the number of polyhedra around the edges is given. So this paper gives a complete list of regular dodecahedral space forms, but in some small classes the difference of the manifolds (up to isometry) cannot be guaranteed yet. www.emis.de /journals/BAG/vol.39/no.2/24.html   (299 words)

 Zero-gravity jet simulates space for regular folks - The Washington Times: Travel - October 30, 2004   (Site not responding. Last check: 2007-11-07) ABOARD G-FORCE ONE ABOVE THE GULF OF MEXICO — Space is the one frontier that's out of reach to the average person, but the feeling of space travel is now a little less elusive. For those who dream of rocketing into space or who just want a new thrill, roller-coaster-type flights aboard a modified jetliner give passengers the sense of walking on the moon and the ability to fly like Superman. It's these maneuvers, rather than the altitude — which is comparable to that of regular commercial flights — that cause the weightless effect. washingtontimes.com /functions/print.php?StoryID=20041029-075940-4763r   (1123 words)

 The Times Herald - News - 01/12/2005 - Township to hold first regular Open Space Committee meeting   (Site not responding. Last check: 2007-11-07) SKIPPACK - Skippack Township is scheduled to hold the first regular meeting of its Open Space Committee, a group charged with writing an open space plan that prioritizes land for acquisition and preservation by leveraging county funds. Though the money is intended for open space acquisition, the county also permits municipalities to build trails, or to spend up to 30 percent of their allotment for historic sites - known as heritage resources - and up to 50 percent on farmland acquisition, DeSipio said. The first task of the group will be writing an open space plan which includes sections evaluating previous open space efforts, assessing current resources and defining open space priorities. www.timesherald.com /site/news.cfm?newsid=13729057&BRD=1672&PAG=461&dept_id=33380&rfi=6   (524 words)
