Let {φn(z) }n∞0 be a series of monic complex polynomials with deg φn = n , such that zn,j ,j = 1,2,--. ,n ,the zeros ofφn ,for each n ≥1, satisfy |z,,j | 〈 1 . We es- tablish the relationship between the orthogonality of such a series, the boundness of a cer- tain ratio and the condition | znj | 〈 1 ,j = 1,2,..-,n.
