P. RAMULU*, G. L. REDDY, C. GANGADHAR

Abstract


In this paper we can extend  the well-known result  Eneström-Kakeya theorem by relaxing the hypothesis in several ways and obtain zero-free regions for polynomials with special complex coefficients and there by present some interesting generalizations and extensions of the Eneström-Kakeya Theorem.


Keywords


Zeros of polynomial, Polar Derivatives, Eneström-Kakeya theorem.
