N2 - Let I = [ 0, d ), where d is finite or infinite. Let Wρ fenced(x) = xρ exp fenced(- Q fenced(x)), where ρ > - frac(1, 2) and Q is continuous and increasing on I, with limit ∞ at d. We obtain further bounds on the orthonormal polynomials associated with the weight Wρ2, finer spacing on their zeros, and estimates of their associated fundamental polynomials of Lagrange interpolation. In addition, we obtain weighted Markov and Bernstein inequalities.
