Orthogonal — Orthogonalité L équation régissant la propagation de la chaleur se résout à l aide de l orthogonalité dans un espace de dimension infinie. En mathématiques, l orthogonalité est un concept d algèbre linéaire associé à une forme bilinéaire. Un cas… … Wikipédia en Français
Orthogonal wavelet — An orthogonal wavelet is a wavelet where the associated wavelet transform is orthogonal. That is the inverse wavelet transform is the adjoint of the wavelet transform. If this condition is weakened you may end up with biorthogonal wavelets.… … Wikipedia
Approximation theory — In mathematics, approximation theory is concerned with how functions can best be approximated with simpler functions, and with quantitatively characterizing the errors introduced thereby. Note that what is meant by best and simpler will depend on … Wikipedia
Orthogonal polynomials — In mathematics, an orthogonal polynomial sequence is a family of polynomials such that any two different polynomials in the sequence are orthogonal to each other under some inner product. The most widely used orthogonal polynomials are the… … Wikipedia
Orthogonal Procrustes problem — The orthogonal Procrustes problem [1] is a matrix approximation problem in linear algebra. In its classical form, one is given two matrices A and B and asked to find an orthogonal matrix R which most closely maps A to B. [2] Specifically … Wikipedia
Approximation in algebraic groups — In mathematics, strong approximation in linear algebraic groups is an important arithmetic property of matrix groups. In rough terms, it explains to what extent there can be an extension of the Chinese remainder theorem to various kinds of… … Wikipedia
FONCTIONS (REPRÉSENTATION ET APPROXIMATION DES) — Il arrive très souvent que, dans les problèmes issus des mathématiques ou des autres sciences, les fonctions qui interviennent soient définies par des procédés qui ne permettent pas d’étudier de manière efficace leurs propriétés. C’est le cas des … Encyclopédie Universelle
Classical orthogonal polynomials — In mathematics, the classical orthogonal polynomials are the most widely used orthogonal polynomials, and consist of the Hermite polynomials, the Laguerre polynomials, the Jacobi polynomials together with their special cases the ultraspherical… … Wikipedia
Interacting Boson Approximation — Bei der Interacting Boson Approximation (IBA) handelt es sich um Näherungsverfahren um die Struktur von Atomkernen zu beschreiben. Oft wird dieses Verfahren auch als Interacting Boson Model (IBM) bezeichnet. Das Modell eignet sich vor allem für… … Deutsch Wikipedia
Singular value decomposition — Visualization of the SVD of a 2 dimensional, real shearing matrix M. First, we see the unit disc in blue together with the two canonical unit vectors. We then see the action of M, which distorts the disk to an ellipse. The SVD decomposes M into… … Wikipedia
Hilbert space — For the Hilbert space filling curve, see Hilbert curve. Hilbert spaces can be used to study the harmonics of vibrating strings. The mathematical concept of a Hilbert space, named after David Hilbert, generalizes the notion of Euclidean space. It… … Wikipedia
