Orthogonal matrix — In linear algebra, an orthogonal matrix (less commonly called orthonormal matrix[1]), is a square matrix with real entries whose columns and rows are orthogonal unit vectors (i.e., orthonormal vectors). Equivalently, a matrix Q is orthogonal if… … Wikipedia
Invariant (mathematics) — In mathematics, an invariant is a property of a class of mathematical objects that remains unchanged when transformations of a certain type are applied to the objects. The particular class of objects and type of transformations are usually… … Wikipedia
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

Invariant measure — In mathematics, an invariant measure is a measure that is preserved by some function. Invariant measures are of great interest in the study of dynamical systems. The Krylov Bogolyubov theorem proves the existence of invariant measures under… … Wikipedia

Arf invariant — In mathematics, the Arf invariant, named after Turkish mathematician Cahit Arf, who introduced it in 1941, is an element of F2 associated to a non singular quadratic form over the field F2 with 2 elements, equal to the most common value of the… … Wikipedia
Curvature invariant (general relativity) — Curvature invariants in general relativity are a set of scalars called curvature invariants that arise in general relativity. They are formed from the Riemann, Weyl and Ricci tensors which represent curvature and possibly operations on them such… … Wikipedia
de Sitter invariant special relativity — In mathematical physics, de Sitter invariant special relativity is the speculative idea that the fundamental symmetry group of spacetime is the Indefinite orthogonal group SO(4,1), that of de Sitter space. In the standard theory of General… … Wikipedia
Indefinite orthogonal group — In mathematics, the indefinite orthogonal group, O( p , q ) is the Lie group of all linear transformations of a n = p + q dimensional real vector space which leave invariant a nondegenerate, symmetric bilinear form of signature ( p , q ). The… … Wikipedia
