Inequalities for the derivative of Polynomials with restricted zeros

Inequalities for the derivative of Polynomials with restricted zeros

In this paper we shall use the boundary Schwarz lemma of Osserman to obtain some generalizations and refinements of some well known results concerning the maximum modulus of the polynomials with restricted zeros due to Turan, Dubinin and others.
