Author(s): Aijaz Ahmad, Muzamil Jallal and Rajnee Tripathi
Abstract: The well-known theorem in theory of distribution of zeros of a polynomial due to Enestrom – Kakeya states that if P(z)=a_n z^n+a_(n-1) z^(n-1)+⋯a_1 z+a_0 be a polynomial of degree n, satisfying a_n≥a_(n-1)≥⋯≥a_1≥a_0>0 Then all the zeroes of P(z) lie in |z|≤1. In this paper we will extend Enestrom – Kakeya theorem by relaxing the restrictions on the coefficients of a polynomial in several ways and thereby present a result on zero free region of a polynomial to certain condition.
