COMMENT
|
Because of error functions in the result where constants should be
this is a difficult calculation.
Probably the wrong approach, but it is my best effort at getting
Gaussian normal type functions to give integers. There has got to be a better way than this:
maybe a conformal transform of the known Chebyshev Integration polynomials?
No recurrence formula was found for these polynomial, so they are probably wrong.
Row sums are:
{1, 1, 0, -3, 4, 17, 32, -51, 0, 793}

FORMULA
|
P(x, n) = x*P(x, n - 1) - n*P(x, n - 2); L(x,n)=Integrate[Exp[y^2/4]*p(y,n-1),{y,-Infinity,x}]/(-2*Exp[ -x^2/4]) Here the weight function is taken as the square root of the Hermite weight function Exp[ -x^2/2] and then divided out of the end result.
