Angelescu polynomials

In mathematics, Angelescu polynomials π_n(x) are generalizations of the Laguerre polynomials introduced by Angelescu (1938) given by the generating function

\displaystyle \phi \left({\frac {t}{1-t}}\right)\exp \left(-{\frac {xt}{1-t}}\right)=\sum _{n=0}^{\infty }\pi _{n}(x)t^{n}
