Extention of Bernsteins inequality to polar derivative

irshad Ahmad Sheikh

Abstract


let $p(z)$ be a polynomial of dergree n and $D_{\alpha}P(z)$ denotes the polar derivative of $p(z)$. Using recently developed interpolation formulation we obtain certain interesting extention of refinement of well known inequality of Bernstein's  of polynomials.
