	Open and closed maps - Wikipedia, the free encyclopedia
		In fact, a bijective continuous map is a homeomorphism iff it's open, or equivalently, iff it's closed.
		In functional analysis, the open mapping theorem states that every surjective continuous linear operator between Banach spaces is an open map.
		In complex analysis, the identically named open mapping theorem states that every non-constant holomorphic function defined on a connected open subset of the complex plane is an open map.

	PlanetMath: classification of topological properties according to behaviour under mapping (Site not responding. Last check: 2007-10-08)
		Since every map may be expressed as the composition of an inclusion and a homomorphism, it is natural to consider the cases where
		A property of a topological space is called continuous if it is the case that, whenever a space has this property, the images of this space under all continuous mapping also have the same property.
		This is version 10 of classification of topological properties according to behaviour under mapping, born on 2004-09-24, modified 2005-08-14.

	Continuity (mathematics) : Continuous (Site not responding. Last check: 2007-10-08)
		In mathematics, a continuous function is one in which "small" changes in the input produce "small" changes in the output.
		A continuous map that is bijective such that its inverse map[?] is also continuous is called a homeomorphism.
		Thisn'tion of continuity is indeed a generalization of the concept for metric spaces: if X and Y are metric spaces and f : X → Y is a function, then f is continuous as a map between metric spaces if and only if it is continuous as a map between topological spaces.

	Map Analysis Topic 18: Understanding Grid-Basd data
		While a contour map might be as familiar and comfortable as a pair of old blue jeans, the generalized intervals treat the data as discrete (ordinal, choropleth).
		However, the histogram and map patterns are identical (slight differences in the maps are an artifact of rounding the discrete display intervals).
		Map normalization is often a forgotten step in the rush to make a map, but is critical to a host of subsequent analyses from visual map comparison to advanced data analysis.

	Abstract
		The existing paper geographical maps are the most suitable for use and also they are the best tools for representing large number of corresponding spatial data.
		We choose continuous raster map coordinate system which is parallel to 7th Gaus-Kruger's zone coordinate system (Gaus-Kruger's zones are 3 degree wide) because it cover the major area of Yugoslavia.
		Dimensions of the paper maps are often larger then the dimensions of available scanner, so the partially scanning of the paper maps is necessary, as well as process of connecting their parts all together.

	Fibrewise General Topology: A Brief Outlook by David Buhagiar
		Collectionwise normal maps were defined by the author [8] and enabled the definition of metrizable type maps, giving a satisfactory fibrewise version of the theory of metrizable spaces.
		In [2, 3], a category of maps MAP in which one does not restrain oneself with a fixed base space Y was studied.

		In topology, two continuous functions from one topological space to another are called homotopic if one can be "continuously deformed" into the other, such a deformation being called a homotopy between the two functions.
		Being homotopic is an equivalence relation on the set of all continuous functions from X to Y.
		In case the two given continuous functions f and g from the topological space X to the topological space Y are homeomorphisms, one can ask whether they can be connected 'through homeomorphisms'.

	Quantitative Methods for Analyzing Map Similarity and Zoning
		The maps generalize the same map surface into discrete zones (white= low, light gray= medium and dark gray= high).
		In vector analysis maps are intersected and aggregating the areas of the son-and-daughter polygons that are derived summarizes the type of disagreement.
		While level slicing and map similarity are useful in examining spatial relationships and data patterns, they require a user to specify data analysis parameters.

	Chapter Four, Continuous Field Uncertainty Models (Site not responding. Last check: 2007-10-08)
		Continuous maps are interval or ratio fields over a (usually) two dimensional surface.
		Because of locational error, comparing the attributes of two continuous maps measuring the same attribute at a point will include both the error from the lower quality map as well as differences in attribute values caused by the misalignment of the two continuous surfaces.
		The technique to generate the parameters of the continuous surface random field model is identical to the continuous surface sample projects in Chapter Five.

		This is indeed a norm since continuous functions defined on a closed interval are bounded.
		L(V, W) is another map between Banach spaces (in general not a linear map!), and can possibly be differentiated again, thus defining the higher derivatives of f.
		As a consequence of the Hahn-Banach theorem, this map is injective; if it is also surjective, then the Banach space V is called reflexive.

	Part One: The Play’s the Thing
		Depending on the implementation, the dataset for the map may be sparse or dense—meaning, the map may actually have data for every point on the grid, or it may only have data for specific landmarks on the grid.
		When you physically move on the map from a location handled by one server to a location handled by another, you and all your belongings are copied over to the other server process transparently and instantly.
		The basic implementation of a continuous map has a low density of grid points, meaning that it is essentially a grid mosaic of individual spaces.

		Each of the maps above is both epi and mono, but at least one of them is not a homeomorphism (isomorphism in the category).

		If the original map is a nonsurjective epimorphism, then the immersion from this factorization will be an epimorphism and an injection, hence a monomorphism, but not an isomorphism.

	Scott is Phoa, locally
		In a paper circulated since end of last year Dana Scott has proposed a category PEQU of algebraic lattices with partial equivalence relations as objects and equivariant Scott continuous maps as morphisms.
		One nice thing about PEQU is that Scott has shown it to be equivalent to the category EQU of T_0 spaces with (total) equivalence relations and equivariant continuous maps.
		It has been shown (by students of Scott) that PEQU is not even well-powered despite being regular and locally cartesian closed (in particular, it is a logos and thus a model for FOL).

		General topology is the study of abstract topological spaces and continuous maps between such spaces.
		The two pillars of general topology are compact spaces and metric spaces and continuous mappings between these spaces.
		As such, the goal of the course is to study compact topological spaces and metric spaces and continuous maps between these spaces.

		An approach to this study consists in restricting our attention to particular classes of continuous maps.
		It is interesting to notice that antitriangular maps appear in connection with an economic model called duopoly (see [3]).
		Finally, in the case of NcLY-antitriangular maps we obtain some consequences about the set \omega(F) of limit points of F which lead us to solve some open questions stated in [1].
