A NOTE ON THE INEQUALITIES FOR A POLYNOMIAL AND ITS DERIVATIVE

pp. 63-69

Abstract

In this paper, we obtain new bounds concerning the maximum moduli of complex polynomials of lacunary type and their derivatives with restricted zeros. These results generalize and refine upon all the earlier results.
