• ZERO-FREE REGIONS FOR POLYNOMIALS WITH RESTRICTED COEFFICIENTS
Abstract
According to a famous result of Enestrom and Kakeya, if is a polynomial of degree n such that , then P(z) does not vanish in In this paper we relax the hypothesis of this result in several ways and obtain zero-free regions for polynomials with restricted coefficients and thereby present some interesting generalizations and extensions of the Enestrom-Kakeya Theorem.
Keywords
Zero-free regions, Bounds, Polynomials.
