Let w be a weight on the unit disk D having the form w(z)=∣v(z)∣2k=1∏s1−zakz−akmk,mk>−2,∣ak∣<1, where v is analytic and free of zeros in D, and let (pn)n=0∞ be the sequence of polynomials (pn of degree n) orthonormal over D with respect to w. We give an integral representation for pn from which it is in principle possible to derive its asymptotic behavior as n→∞ at every point z of the complex plane, the asymptotic analysis of the integral being primarily dependent on the nature of the first singularities encountered by the function v(z)−1∏k=1s(1−zak)−1.
