The study of the zeros of polynomials has a very rich history. In addition to having numerous
applications, this study has been the inspiration for much theoretical research (including …

Let a monic polynomial Pn (x)≔ xn− a1xn-1−···− an, aj∈% plane1D; 49E; j= 1, 2,…, n, be
given. Bounds for the eigenvalues and the computation of the singular values of some …

For the polynomial P (z)= ajzj, aj≥ aj-1, a0> 0, j= 1, 2,…, n, an> 0, a classical result of
Eneström-Kakeya says that all the zeros of P (z) lie in| z|≤ 1. This result was generalised by …

In this paper, we put restrictions on the coefficients of polynomials and give bounds
concerning the number of zeros in a specific region. Our results generalize a number of …

Sažetak Let P (z) be a polynomial of degree n with real or complex coefficients. In this paper
we obtain a ring shaped region containing all the zeros of P (z). Our result include, as …

In this paper we prove some extension of the Eneström-Kakeya theorem by relaxing the
hypothesis of this result in several ways and obtain zero-free regions for polynomials with …

In this manuscript, we are concerned with the problem of locating the zeros of some special
quaternionic polynomials and regular functions with restricted coefficients; namely …
