Boas–Buck polynomials
From HandWiki
In mathematics, Boas–Buck polynomials are sequences of polynomials [math]\displaystyle{ \Phi_n^{(r)}(z) }[/math] defined from analytic functions [math]\displaystyle{ B }[/math] and [math]\displaystyle{ C }[/math] by generating functions of the form
- [math]\displaystyle{ \displaystyle C(zt^r B(t))=\sum_{n\ge0}\Phi_n^{(r)}(z)t^n }[/math].
The case [math]\displaystyle{ r=1 }[/math], sometimes called generalized Appell polynomials, was studied by Boas and Buck (1958).
