 [No title]   (Site not responding. Last check: 2007-11-06) In mathematics, a linear transformation (also called linear operator or linear map) is a function between two vector spaces that respects the arithmetical operations addition and scalar multiplication defined on vector spaces, or, in other words, it "preserves linear combinations". For instance, the integral yields a linear map from the space of all real-valued integrable functions on some interval to R, while differentiation is a linear transformation from the space of all differentiable functions to the space of all functions. In the finite dimensional case and if bases have been chosen, then the composition of linear maps corresponds to the multiplication of matrices, the addition of linear maps corresponds ot the addition of matrices, and the multiplication of linear maps with scalars corresponds to the multiplication of matrices with scalars. www.informationgenius.com /encyclopedia/l/li/linear_transformation.html   (640 words)

Last check: 2007-11-06) Linear algebra is the branch of mathematics concerned with the study of vectorss, vector spaces (or linear spaces), linear transformations, and systems of linear equations. Linear algebra today has been extended to consider n-space, since most of the useful results from 2 and 3-space can be extended to n-dimensional space, but we may also use linear algebra to investigate infinite-dimensional spaces. Some striking examples of this are the group of invertible linear maps or matrices, and the ring of linear maps of a vector space. www.onlineencyclopedia.org /l/li/linear_algebra_1.html   (809 words)

 Linear algebra Article, Linearalgebra Information   (Site not responding. Last check: 2007-11-06) Linear algebra is the branch of mathematics concernedwith the study of vectors, vector spaces (or linear spaces), linear transformations, and systems of linear equations. Linear operators take elementsfrom a linear space to another (or to itself), in a manner that is compatible with the addition and scalar multiplication givenon the vector space(s). The general method of finding a linear way to look at a problem, expressing this in terms of linear algebra, and solving it,if need be by matrix calculations, is one of the most generally applicable in mathematics. www.anoca.org /space/vector/linear_algebra.html   (792 words)

 Linear algebra   (Site not responding. Last check: 2007-11-06) Linear operators take elements from a linear space to another (or to itself), in a manner that is compatible with the addition and scalar multiplication given on the vector space(s). If a basis for a vector space is fixed, every linear transform can be represented by a table of numbers called a matrix. A matrix is non-singular iff the linear transformation represented by the matrix is isomorphism. www.sciencedaily.com /encyclopedia/linear_algebra_1   (848 words)

 Help -- Linear Maps   (Site not responding. Last check: 2007-11-06) The marker order shown in the linear maps is identical to the 2D-map marker order, i.e., map order was determined using 2RR (the two-recombinant rule) and the transitive properties of ordered markers; markers were NOT ordered using likelihood methods used by multipoint linkage programs such as CRI-MAP. Map orientation: the p-terminal end of the chromosome is at the top, running down through the centromere region, and continues to the q-terminal regions. The segments are scaled to correspond to marker positions on the linear map (the heavy line with tie-lines to marker names). www.genlink.wustl.edu /mmp/help_linear_map.html   (256 words)

 New York State Library: Annotated Bibliography of Selected New York State Maps: 1793-1900   (Site not responding. Last check: 2007-11-06) Map production responded to pressing needs, particularly transportation information: canal maps in the 1820's and 1830's, railroad maps and travellers' guides from the 1830's to the turn of the century, large scale county maps in the mid 1800s, cyclists' and thematic (economic and geological) maps by the 1890's. Maps were reversed on a soft copper plate and the original engraved to produce a backwards-reading intaglio template. Maps have particular problems in terms of "authorship" and "copyright", for a map may be copied with minor changes and become the "property" of a new author, or the publisher may buy the copyright from the author. www.nysl.nysed.gov /msscfa/mapsbibl.htm   (10868 words)

 Linear Maps   (Site not responding. Last check: 2007-11-06) In particular we will focus on linear maps, and we will see that linear maps may be used to solve many types of problems in mathematics including dynamical systems and Markov processes. In particular we will discover that every linear map between vector spaces may be represented by a matrix. This is the fourth abstraction, and it will allow us to analyse linear maps by their matrix representation. isolatium.uhh.hawaii.edu /linear/Maps.htm   (115 words)

 The Linear Topic Map Notation The XML-based topic map interchange format is defined in such a way as to make it easy to understand for humans and to develop software for, and these purposes it fulfills very well. Humans were not really intended to do this, of course, they were intended to use specialized topic map editors, which would insulate their users from the syntactical details of the interchange format. This directive causes the topic map at the given URI to be loaded according to the rules of the syntax it is written in and merged with the current topic map once the loading is complete. www.ontopia.net /download/ltm.html   (3704 words)

 Linear maps: formulae explained   (Site not responding. Last check: 2007-11-06) We are given a formula F(X) supposed to define a linear map in 2 dimensions, say. Suppose that the formula has been shown to describe some linear map, but we want to show that it describes a specific linear map f (such as perpendicular projection onto a line OP). This is because F and f are both linear, and P and Q are a basis. www.maths.tcd.ie /~odunlain/1ba1/linmaps   (219 words)

The sequence {Xk} produced by the maps is mapped into the interval [-1,-1] to be used as waveform.

 Iterations of linear maps over finite fields - abstract   (Site not responding. Last check: 2007-11-06) We show that the cyclic dynamics of both maps in dimension 2n can be deduced from their periodic behavior in dimension n. This link is generalized to a larger class of maps.
