In mathematics, especially in algebraic number theory, the Hermite–Minkowski theorem states that for any integer ''N'' there are only finitely many number fields, i.e., finite field extensions ''K'' of the rational numbers Q, such that the discriminant of ''K''/Q is at most ''N''. The theorem is named after Charles Hermite and Hermann Minkowski. This theorem is a consequence of the estimate for the discriminant : where ''n'' is the degree of the field extension, together with Stirling's formula for ''n'' ==References== Section III.2 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「Hermite–Minkowski theorem」の詳細全文を読む スポンサード リンク
