Other orthogonal polynomials, Laguerre polynomials

These polynomials arise from the solution of the differential equation \begin{equation*} \left(\frac{d^2 }{dx^2}-\frac{d }{dx}+\frac{\lambda}{x}-\frac{l(l+1)}{x^2}\right){\cal L}(x)=0, \end{equation*} where l is an integer l\ge 0 and \lambda a constant. This equation arises for example from the solution of the radial Schr\"odinger equation with a centrally symmetric potential such as the Coulomb potential.
