Look up invariance, invariant, or invariants in Wiktionary, the free dictionary. Invariant and invariance may refer to: Invariant (computer science),...
The invariant mass, rest mass, intrinsic mass, proper mass, or in the case of bound systems simply mass, is the portion of the total mass of an object...
class invariant (or type invariant) is an invariant used for constraining objects of a class. Methods of the class should preserve the invariant. The class...
giving readers the rights to copy, redistribute, and modify (except for "invariant sections") a work and requires all copies and derivatives to be available...
In computer science, a loop invariant is a property of a program loop that is true before (and after) each iteration. It is a logical assertion, sometimes...
The invariant speed or observer invariant speed is a speed which is measured to be the same in all reference frames by all observers. The invariance of...
In mathematics, an invariant subspace of a linear mapping T : V → V i.e. from some vector space V to itself, is a subspace W of V that is preserved by...
In optics the Lagrange invariant is a measure of the light propagating through an optical system. It is defined by H = n u ¯ y − n u y ¯ {\displaystyle...
In mathematics, the Arf invariant of a nonsingular quadratic form over a field of characteristic 2 was defined by Turkish mathematician Cahit Arf (1941)...
Invariant theory is a branch of abstract algebra dealing with actions of groups on algebraic varieties, such as vector spaces, from the point of view...
In mathematics, the Dickson invariant, named after Leonard Eugene Dickson, may mean: The Dickson invariant of an element of the orthogonal group in characteristic...
dynamical systems, a branch of mathematics, an invariant manifold is a topological manifold that is invariant under the action of the dynamical system. Examples...
In mathematics, the Kervaire invariant is an invariant of a framed ( 4 k + 2 ) {\displaystyle (4k+2)} -dimensional manifold that measures whether the...
mathematics, in particular in algebraic topology, the Hopf invariant is a homotopy invariant of certain maps between n-spheres. In 1931 Heinz Hopf used...
In geometry, the Dehn invariant is a value used to determine whether one polyhedron can be cut into pieces and reassembled ("dissected") into another...
context. However, while moment invariants are invariants that are formed from moments, the only moments that are invariants themselves are the central moments...
fields of multilinear algebra and representation theory, the principal invariants of the second rank tensor A {\displaystyle \mathbf {A} } are the coefficients...
In the mathematical field of knot theory, a knot invariant is a quantity (in a broad sense) defined for each knot which is the same for equivalent knots...
hyperboloids. The invariant hyperbolae displaced by spacelike intervals from the origin generate hyperboloids of one sheet, while the invariant hyperbolae displaced...
circular angle is invariant under rotation, hyperbolic angle is invariant under squeeze mapping, and a difference of slopes is invariant under shear mapping...
approximately constant when changes occur slowly is called an adiabatic invariant. By this it is meant that if a system is varied between two end points...
The invariant factors of a module over a principal ideal domain (PID) occur in one form of the structure theorem for finitely generated modules over a...
closely related concept is self-similarity, where a function or curve is invariant under a discrete subset of the dilations. It is also possible for the...
expression, formed from items of the theory, which evaluates to a scalar, invariant under any Lorentz transformation. A Lorentz scalar may be generated from...
