Gould polynomials explained

In mathematics the Gould polynomials Gn(x; a,b) are polynomials introduced by H. W. Gould and named by Roman in 1984.They are given by [1]

\displaystyle\exp(xf-1(t))=

infty
\sum
n=0
G
n(x;a,b)tn
n!
where

f(t)=eat(ebt-1)

so

f-1(t)=

1
b
infty
\sum\binom{-(b+ak)/b}{k-1}
k=1
tk
k
