摘要：

Let P(z) = anzn + an-1zn-1 + + a0 be a complex polynomial of degree n. There is a close connection between the coefficients and the zeros of P(z). In this paper we prove some sharp inequalities concerning the coeffi- cients of the polynomial P(z) with restricted zeros. We also establish a sufficient condition for the separation of zeros of P(z).
