There has got to be a better way than this: maybe a conformal transform of the known Chebyshev Integration polynomials? %C A136239 No recurrence formula was found for these polynomials, so they are probably wrong. %C A136239 Row sums are: %C A136239 {1, 1, 0, -3, 4, 17, 32, -51, 0, 793} %D A136239 page 8 and pages 42 - 43 : Harry Hochstadt, The Functions of Mathematical Physics, Dover, New York, 1986 %F A136239 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. %e A136239 {1}, %e A136239 {0, 1}, %e A136239 {-1, 0, 1}, %e A136239 {-1, -3, 0, 1}, %e A136239 {9, 0, -6, 0, 1}, %e A136239 {-1, 27, 0, -10, 0, 1}, %e A136239 {-19, 0, 65, 0, -15, 0, 1}, %e A136239 {-1, -165, 0, 135, 0, -21, 0,1}, %e A136239 {399, 0, -624, 0, 252, 0, -28, 0, 1}, %e A136239 {-1, 2145, 0, -1750, 0, 434, 0, -36, 0, 1} %Y A136239 Cf.
