Induced Character
In mathematics, an induced character is the character of the representation ''V'' of a finite group ''G'' induced from a representation ''W'' of a subgroup ''H'' ≤ ''G''. More generally, there is also a notion of induction \operatorname(f) of a class function ''f'' on ''H'' given by the formula :\operatorname(f)(s) = \frac \sum_ f(t^ st). If ''f'' is a character of the representation ''W'' of ''H'', then this formula for \operatorname(f) calculates the character of the induced representation ''V'' of ''G''.. Translated from the second French edition by Leonard L. Scott. The basic result on induced characters is Brauer's theorem on induced characters Brauer's theorem on induced characters, often known as Brauer's induction theorem, and named after Richard Brauer, is a basic result in the branch of mathematics known as character theory, within representation theory of a finite group. Backgrou .... It states that every irreducible character on ''G'' is a linear combination w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...
