Abstract: We investigate the asymptotic behavior of polynomials orthonormal over regions G in the complex plane with respect to area measure (Bergman polynomials) in the case when G=NUJ=1 Gj consists of the finite union of N≥2 mutually exterior Jordan domains. Our results concern the limiting behavior of the zeros of these polynomials as well as fine estimates for their leading co-efficients. We also discuss a technique for the reconstruction of the component domains Gj from the area moments over G. (Joint work with B. Gustafsson, M. Putinar and N. Stylianopoulos.)
