In mathematics, the two families ''c''(''x'';''k'') and ''B''(''x'';''k'') of sieved ultraspherical polynomials, introduced by Waleed Al-Salam, W.R. Allaway and Richard Askey in 1984, are the archetypal examples of sieved orthogonal polynomials. Their recurrence relations are a modified (or "sieved") version of the recurrence relations for ultraspherical polynomials. ==Recurrence relations== For the sieved ultraspherical polynomials of the first kind the recurrence relations are : if ''n'' is not divisible by ''k'' : For the sieved ultraspherical polynomials of the second kind the recurrence relations are : if ''n'' is not divisible by ''k'' : 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「sieved ultraspherical polynomials」の詳細全文を読む スポンサード リンク
