In algebra, the Amitsur–Levitzki theorem states that the algebra of ''n'' by ''n'' matrices satisfies a certain identity of degree 2''n''. It was proved by . In particular matrix rings are polynomial identity rings such that the smallest identity they satisfy has degree exactly 2''n''. ==Statement== The standard polynomial of degree ''n'' is : in non-commutative variables ''x''1,...,''x''''n'', where the sum is taken over all ''n''! elements of the symmetric group ''S''''n''. The Amitsur–Levitzki theorem states that for ''n'' by ''n'' matrices ''A''1,...,''A''2''n'' then : 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「Amitsur–Levitzki theorem」の詳細全文を読む スポンサード リンク
