Denisyuk polynomials

In mathematics, Denisyuk polynomials De_n(x) or M_n(x) are generalizations of the Laguerre polynomials introduced by (Denisyuk 1954) given by the generating function^[1] $${\displaystyle {\displaystyle {\displaystyle \sum _{n=0}^{\mathrm{\infty }}}{t}^n{M}_n(x)=\frac{1}{1+t}\exp -\frac{xt}{1-t}.}}$$
