In mathematics, the term Beurling algebra is used for different algebras introduced by , usually it is an algebra of periodic functions with Fourier series : Example We may consider the algebra of those functions ''f'' where the majorants : of the Fourier coefficients ''a''''n'' are summable. In other words : Example We may consider a weight function ''w'' on such that : in which case is a unitary commutative Banach algebra. These algebras are closely related to the Wiener algebra. ==References== * * 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「Beurling algebra」の詳細全文を読む スポンサード リンク
