On the derivative and maximum modulus of a polynomial

Abstract

If is a polynomial of degree, having all its zeros in, then it was proved by Turán that. This result of Turán was generalized by Govil, who proved that if has all its zeros in,, then,. In this paper, we sharpen this, and some other related results.
