Boas–Buck polynomials

In mathematics, Boas–Buck polynomials are sequences of polynomials $$\Phi_n^{(r)}(z)$$ defined from analytic functions $$B$$ and $$C$$ by generating functions of the form


 * $$\displaystyle C(zt^r B(t))=\sum_{n\ge0}\Phi_n^{(r)}(z)t^n$$.

The case $$r=1$$, sometimes called generalized Appell polynomials, was studied by.
