摘　　要：Let p(z)be a polynomial of degree n having some zeros at a point z0 ∈C with |z0|<1 and the rest of the zeros lying on or outside the boundary of a prescribed disk.In this brief note,we consider this class of polynomials and obtain some bounds for(max|z|=R|p(z)|)s in terms of (max|z|=1|p(z)|)s for any R≥1 and s∈N.
