The orthogonal group of a non-singular quadratic form Q is the group of the linear automorphisms of V that preserve Q: that is, the group of isometries of (V, Q) into itself. If a quadratic space ( A , Q ) has a product so that A is an algebra over a field , and satisfies ∀ x , y ∈ A Q ( x y ) = Q ( x ) Q ( y ) , {\displaystyle \forall x,y ...
Group theory has three main historical sources: number theory, the theory of algebraic equations, and geometry. The number-theoretic strand was begun by Leonhard Euler, and developed by Gauss's work on modular arithmetic and additive and multiplicative groups related to quadratic fields.
The manipulations of the Rubik's Cube form the Rubik's Cube group.. In mathematics, a group is a set with an operation that associates an element of the set to every pair of elements of the set (as does every binary operation) and satisfies the following constraints: the operation is associative, it has an identity element, and every element of the set has an inverse element.
The fee of 30 USD also applies when the visa is obtained in advance. China is lifted to Group 2 Country effective on August 17, 2014. Chinese nationals can get visa on arrival at airport or land check points as indicated by Bolivian Embassy in Beijing on December 27, 2017.

The Open Group Architecture Framework (TOGAF) is the most used framework for enterprise architecture as of 2020 [2] that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. [3] TOGAF is a high-level approach to design. It is typically modeled at four levels: Business ...
SL (2, R) is a real, non-compact simple Lie group, and is the split-real form of the complex Lie group SL (2, C). The Lie algebra of SL (2, R), denoted sl (2, R), is the algebra of all real, traceless 2 × 2 matrices. It is the Bianchi algebra of type VIII.
The SU(n) groups find wide application in the Standard Model of particle physics, especially SU(2) in the electroweak interaction and SU(3) in quantum chromodynamics. [1] The simplest case, SU(1), is the trivial group, having only a single element. The group SU(2) is isomorphic to the group of quaternions of norm 1, and is thus diffeomorphic to ...
The symmetric group on a finite set is the group whose elements are all bijective functions from to and whose group operation is that of function composition. [1] For finite sets, "permutations" and "bijective functions" refer to the same operation, namely rearrangement. The symmetric group of degree is the symmetric group on the set .
