An application of Gelfand's formula in approximating the roots of polynomials
An application of Gelfand's formula in approximating the roots of polynomials
The purpose of this paper is to show how Gelfand's formula and balancing can be used to improve the upper and lower bounds of the spectrum of a companion matrix associated with a given real or complex polynomial. Examples and other related ideas are provided.
