A note on the location of polynomial roots

Numerical Analysis 2007-05-23 v1

Abstract

We review some known inclusion results for the roots of a polynomial, and adapt them to a conjecture recently presented by S. A. Vavasis. In particular, we provide strict upper and lower bounds to the distance of the closest root of a polynomial p(z) from a given root of p'(z).
