Bijection, injection and surjection - Wikipedia, the free encyclopedia Injective composition: the second function doesn't need to be injective. Surjective composition: the first function doesn't need to be surjective. In mathematics, injections, surjections and bijections are classes of functions distinguished by the manner in which arguments (input expressions) and images (output expressions) are related. en.wikipedia.org /wiki/Injective_function

RDEGRAAF.nl [Mathematics: Moebius Transformation] It can be shown that the inverse, and composition of two mobius transformations are similarly defined, and so the Möbius transformations form a group under composition. then it can be shown that a Möbius transformation maps circles to circles, by looking at each elementary transformation. Any Möbius map can be composed from the elementary transformations - dilations, translations and inversions. www.rdegraaf.nl /index.asp?sND_ID=668568

modern music, composition, experimental music, mathematics musical composition, modernism, the future of modern music, james mchard McHard has guest lectured several times on experimental music, and on mathematics in musical composition. It usually involves experimentation; the experimentation yields special discoveries that bear fruit in the act of composition. This profoundly physical concept needed high-powered mathematics to constrain the movements of the (analogous) sound ‘particles’ and make them faithful to the concept Xenakis had in mind. www.futureofmodernmusic.com /article-1.html   (4367 words)

Ergodic Theory and Geometric Rigidity and Number Theory Ergodic theory is an area of mathematics with all of its roots and development contained within the 20th century. The central scientific theme of this programme was the recent development of applications of ergodic theory to other areas of mathematics, in particular, the connections with geometry, group actions and rigidity, and number theory. Foremost amongst the recent contributions of ergodic theory to number theory is the solution of the Oppenheim Conjecture, a problem on quadratic forms which had been open since 1929. www.newton.cam.ac.uk /reports/9900/ern.html   (4367 words)

The Daily Northwestern - Biennial award for composers to grant $100,000, residency The Nemmers Prize in musical composition follows similar prizes given in economics and mathematics that were established by the late Erwin Nemmers and Frederic Nemmers in 1994. The winner of the biennial Michael Ludwig Nemmers Prize in Musical composition, one of the world's largest awards for composers, will also be given a four-week residency at the School of Music and a performance with the Chicago Symphony Orchestra, in addition to the cash prize. The prize marks a significant collaboration with the Chicago Sympnony Orchestra, something which School of Music Dean Toni-Marie Montgomery said in an Oct. 27 press release she hoped would "strengthen the bonds" between NU and the orchestra. www.dailynorthwestern.com /vnews/display.v/ART/2003/11/13/3fb31f3f41a85   (4367 words)

[20040901] MATHEMATICS AND MUSIC In Western Civilization Mathematics and Music have a long and interesting history in common, with several interactions, traditionally associated with the name of Pythagoras but also with a significant number of other mathematicians, like Leibniz, for instance. Mathematical models can be found for almost all levels of musical activities from composition to sound production by traditional instruments or by digital means. The authors illustrate the rich and deep interactions that exist between Mathematics and Music. www.ticmundi.com /array/3-540-43727-4.html   (159 words)

Articles - Witold Lutosławski In 1931 Lutosławski enrolled at Warsaw University to study mathematics, and formally entered composition classes at the Conservatory. In 1933 he gave up his mathematics and violin studies in order to concentrate on piano and composition. World War II Military service followed Ă˘Â€” Lutosławski was trained in signalling and radio operating, his musical expertise helping him to prove adept at the speedy transmission of messages in Morse code. www.noist.com /articles/Witold_Lutoslawski   (159 words)

Composition - Wikipedia, the free encyclopedia In mathematics, function composition is an operation that takes two (or more) functions as arguments and gives a function as the result. In natural science, composition is the proportion and combination of certain elements to form a substance. In literature, oratory, and rhetoric, composition refers, as the etymology of the word quite literally indicates, to the "putting (words) together" to produce a work of spoken tradition or written literature. en.wikipedia.org /wiki/Composition   (321 words)

Composition series - Wikipedia, the free encyclopedia In mathematics, a composition series of a group G is a normal series If a composition series exists for a group G, then any normal series of G can be refined to a composition series, informally, by inserting subgroups into the series up to maximality. That is, they have the same composition length and the same composition factors, up to permutation and isomorphism. en.wikipedia.org /wiki/Composition_series   (212 words)

Differential geometry and topology - Open Encyclopedia We say a function from the manifold to R is infinitely differentiable if its composition with every homemorphism results in an infinitely differentiable function from the open unit ball to R. A vector field is a function from a manifold to the disjoint union of its tangent spaces (this union is itself a manifold known as the tangent bundle), such that at each point, the value is an element of the tangent space at that point. Initially and up to the middle of the nineteenth century, differential geometry was studied from the extrinsic point of view: curves, surfaces were considered as lying in a Euclidean space of higher dimension (for example a surface in an ambient space of three dimensions). open-encyclopedia.com /Differential_geometry   (982 words)

Jean Piaget's Genetic Epistemology Towards the understanding of mathematical development, Piaget conducted various experiments in which he provided tactual representations of mathematical concepts such as conservation of quantities, one-one correspondence, ordination, cardination, classification, and additive and multiplicative composition of numbers. Fortunately, the field of mathematics has effectively minimized their importance. Deductive reasoning should follow from experience with the mathematical entities, and from this the understanding of mathematics. www.math.ufl.edu /dept_news_events/long/essays/baskovich.html   (982 words)

Vedic Ganita In a nutshell, the conclusions are that the mathematics precedes the composition of Rigveda Samhita. Mathematics is called the queen of sciences and is the fundamental base on which all planning is done and all structures are raised. Vedic Mathematics, helped to transform the Universal set of knowledge as a speaking language and in the process itself as well stood transformed as such and assimilated its identity into the Vedas. www.vedicganita.org /transcendental.htm   (4717 words)

Transcendence (mathematics) - Wikipedia, the free encyclopedia In mathematics, a transcendental function is a function which is not expressible as a composition of a finite number of elementary operations, or inverses of functions so constructible, where the elementary operations consist of addition, multiplication, taking additive or multiplicative inverses, and integer root extraction. Transcendental functions include all the trigonometric functions and logarithmic functions, along with most other special functions in mathematics. A transcendental number is a real number that is not a zero of any polynomial with rational coefficients. en.wikipedia.org /wiki/Transcendence_(mathematics)   (4717 words)

Encyclopedia: Category theory In mathematics, especially the many applications of category theory, a commutative diagram is a diagram of objects and morphisms such that, when picking two objects, one can follow any path through the diagram and obtain the same result by composition. In mathematics (especially algebraic topology and abstract algebra), homology (in Greek homos = identical) is a certain general procedure to associate a sequence of abelian groups or modules to a given mathematical object (such as a topological space or a group). In mathematics, an automorphism is an isomorphism from a mathematical object to itself. www.nationmaster.com /encyclopedia/category-theory   (4301 words)

Interaction of Finite Dimensional Algebras with other areas of Mathematics Methods concerning quivers and their representations have been used in the past 30 years extensively in order to describe the structure of length categories (abelian categories where every object has a finite composition series) which arise very frequently not only in algebra, but also in geometry and analysis. These algebras may be viewed as generalizations of quiver algebras more appropriate for understanding the standard module/irreducible module relationship in the category$\Cal O$, perverse sheaves, and categories of representations of algebraic groups in positive characteristic. Tilting modules, an older development originating in quiver theory, now impact many areas of representation theory, especially characteristic p, through work of Ringel, Donkin, Soergel and Andersen, for example, and have even proved useful for the study of maximal subgroups of finite groups of Lie type (Seitz, Saxl). www.pims.math.ca /birs/workshops/2004/04w5501   (1166 words)

modern music, composition, experimental music, mathematics musical composition, modernism, the future of modern music, james mchard Modern music is the music composed that results from research into the attributes of sound, and into the ways we perceive sound. This music that we can and must create provides a crucible in which the magic within our souls is brewed, and it is this that frames the templates that guide our very evolution in creative thought. From the standpoint of the musical classroom, two things about Xenakis are most troubling: one is his relative lack of formal musical training; the other, or flip side, is his scientifically oriented schooling background. www.futureofmodernmusic.com /article-1.html   (4367 words)

Art Department Although a dance major is only available as an interdisciplinary major in combination with other subjects, graduates in such diverse majors as classics, biology, psychology, anthropology, and mathematics have entered graduate programs in dance, many with fellowships and grants. Students are encouraged to draw connections between choreography and analogous processes in other disciplines such as writing, music composition, and the creation of visual art and theater. The history and theory classes (Dance 321, 322, and 330) are lecture/conference courses that examine the development of the Western concert dance tradition as well as the critical theory that has developed in the dance field since the nineteenth century. www.reed.edu /academic/catalog/71.html   (1217 words)

The Daily, Tuesday, December 7, 2004. Performance of Canada's youth in mathematics, reading, science and problem solving A student's family background, as well as the composition of their schools, was a factor in performance in mathematics. Canadian 15-year-old students are among the best in the world when it comes to mathematics, reading, science and problem solving, according to a major new international study that assesses the skill level of students nearing the end of their compulsory education. The study showed that while boys outperformed girls in mathematics, the magnitude of the difference in Canada was small. www.statcan.ca /Daily/English/041207/d041207a.htm   (1391 words)

Nuggets from Vedic Mathematics The term Vedic Mathematics refers to a set of sixteen mathematical formulae or sutras and their corollaries derived from the Vedas. A number was encoded using consonant groups of the Sanskrit alphabet, and vowels were provided as additional latitude to the author in poetic composition.

History of Logic Instead of using sets and elements of sets as primitive concepts the categorical view on the foundations of mathematics uses functions and composition of functions as primitive concepts. This lead to a foundation of mathematics which has a very different flavor than the one based on set theory but which can be shown to be essentially equivalent. While topos theory can be seen as alternative to the standard foundation of mathematics. www.a2ii.com /GaloisHelp/TheBook/HistoryOfLogic.htm   (742 words)

THE RELATIONSHIP OF INTERNAL LOCUS OF CONTROL First-year female students (N=93) enrolled in composition classes and mathematics classes at the University of Mary Hardin-Baylor were pretested. Strengthening the internal locus of control in female students may be related to improving achievement of female students and may point towards a solution for the problem of female under-achievement and under-representation. This study defines "locus of control" as that which identifies the extent to which a person perceives that events in her life are contingent upon her own behavior or her own characteristics. www.dianehoward.com /Dissertation.htm   (15984 words)

Practical Foundations of Mathematics In Set, image factorisation is stable: this is necessary in Lemma 5.8.6 to make relational composition associative, and in Theorem 9.3.11 for the existential quantifier to be invariant under substitution. Y, let q:X\twoheadrightarrow Q be the coequaliser of the kernel pair K\rightrightarrows X of f; by Lemma 5.6.6(b) this is also the kernel pair of q. From Lemma 5.7.6(a) it follows that all epis are regular. www.geocities.com /yury_bendersky/b/f/s57.html   (1337 words)
