Frobenius's theorem (group theory) : ウィキペディア英語版 | Frobenius's theorem (group theory) In mathematical group theory, Frobenius's theorem states that if ''n'' divides the order of a finite group ''G'', then the number of solutions of ''x''''n''=1 is divisible by ''n''. It was introduced by . ==Statement==
A more general version of Frobenius's theorem states that if ''C'' is a conjugacy class with ''h'' elements of a finite group ''G'' with ''g'' elements and ''n'' is a positive integer, then the number of elements ''g'' such that ''g''''n'' is in ''C'' is a multiple of the greatest common divisor (''hn'',''g'').
