In mathematics, the dual Hahn polynomials are a family of orthogonal polynomials in the Askey scheme of hypergeometric orthogonal polynomials. They are defined in terms of generalized hypergeometric functions by : for 0≤''n''≤''N'' where λ(''x'')=''x''(''x''+γ+δ+1). give a detailed list of their properties. Closely related polynomials include the Hahn polynomials, the continuous Hahn polynomials ''p''''n''(''x'',''a'',''b'', , ), and the continuous dual Hahn polynomials ''S''''n''(''x'';''a'',''b'',''c''). These polynomials all have ''q''-analogs with an extra parameter ''q'', such as the q-Hahn polynomials ''Q''''n''(''x'';α,β, ''N'';''q''), and so on. ==Orthogonality== 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「Dual Hahn polynomials」の詳細全文を読む スポンサード リンク
