On the $s^{th}$ Derivative of a Polynomial-II
A. Mir , Q.M. Dawood, B. Dar
Abstract:  

The paper presents an $L^{r}-$ analogue of an inequality regarding the $s^{th}$ derivative of a polynomial having zeros outside a circle of arbitrary radius but greater or equal to one. Our result provides improvements and generalizations of some well-known polynomial inequalities.

Keywords: Polynomial, Zeros, $s^{th}$ derivative
