چکیده
|
In this paper, we establish some upper bound estimates for the maximum modulus of the higher order derivative of a polynomial with restricted zeros on a circle of |z| = r, r ≥ 1, in terms of the maximum modulus of the same polynomial on the unit circle |z| = 1. these results generalize and sharpen some known results in this direction.
