Bounds For The Maximum Modulus of Polynomials With Restricted Zeros
Roshan Lal
Abstract :
Let be a polynomial of degree . Concerning the estimate for the maximum modulus of a polynomial on the circle z = R, R > 0 , in terms of its degree and the maximum modulus on the unit circle, we have several well known results for the case R ≥ 1 and r ≥ 1 respectively. In this paper, we have obtained bounds for the maximum modulus of polynomials having some zeros in the interior of a circle of radius R ≥ 1 . Our result improves as well as generalizes the bounds obtained by other authors for the same class of polynomials.
