Lommel polynomial

Lommel polynomial

A Lommel polynomial "R""m",ν("z"), introduced by harvs|txt|authorlink=Eugen von Lommel|first=Eugen von|last= Lommel|year=1871, is a polynomial in 1/"z" giving the recurrence relation :displaystyle J_{m+ u}(z) = J_ u(z)R_{m, u}(z) - J_{ u-1}(z)R_{m-1, u+1}(z) where "J"ν("z") is a Bessel function of the first kind.

They are given explicitly by:R_{m, u} = sum_{n=0}^{ [m/2] }frac{(-1)^m(m-n)!Gamma( u+m-n)}{n!(m-2n)!Gamma( u+n)}(z/2)^{2n-m}.
