摘要：

We find bounds for the polynomials pn(x) orthogonal with respect to asymmetric Freud weights of the form w(x) = exp(-Q(x)), where Q is an even degree polynomial with positive leading coefficient, by utilizing asymptotics for the recursion coefficients an and bn and an approximate differential equation satisfied by pn(x). © 1990.
