Pincherle polynomials

From HandWiki

In mathematics, the Pincherle polynomials Pn(x) are polynomials introduced by S. Pincherle (1891) given by the generating function

[math]\displaystyle{ \displaystyle (1-3xt+t^3)^{-1/2}=\sum^\infty _{n=0}P_n(x)t^n }[/math]

Humbert polynomials are a generalization of Pincherle polynomials
