:''There also is Brauer's theorem on induced characters.'' In mathematics, Brauer's theorem, named for Richard Brauer, is a result on the representability of 0 by forms over certain fields in sufficiently many variables.〔R. Brauer, ''A note on systems of homogeneous algebraic equations'', Bulletin of the American Mathematical Society, 51, pages 749-755 (1945)〕 ==Statement of Brauer's theorem== Let ''K'' be a field such that for every integer ''r'' > 0 there exists an integer ψ(''r'') such that for ''n'' ≥ ψ(r) every equation : has a non-trivial (i.e. not all ''x''''i'' are equal to 0) solution in ''K''. Then, given homogeneous polynomials ''f''1,...,''f''''k'' of degrees ''r''1,...,''r''''k'' respectively with coefficients in ''K'', for every set of positive integers ''r''1,...,''r''''k'' and every non-negative integer ''l'', there exists a number ω(''r''1,...,''r''''k'',''l'') such that for ''n'' ≥ ω(''r''1,...,''r''''k'',''l'') there exists an ''l''-dimensional affine subspace ''M'' of ''Kn'' (regarded as a vector space over ''K'') satisfying : 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Brauer's theorem on forms」の詳細全文を読む スポンサード リンク
