Bernstein and Turán-type inequalities for a polynomial with constraints on its zeros

Abstract This paper considers the well known Bernstein and Turán-type inequalities that relate the uniform norm of a polynomial to that of its derivative on the unit circle in the plane. Here, we establish some new inequalities that relate the uniform norm of the polar derivative and the polynomial,...
