New annuli for the zeros of polynomials


The purpose of this paper is to present a new annulus containing all the zeros of a polynomial using a new identity involving generalized Fibonacci numbers. This new annulus is related to two parameters. By examples, it is shown that this new annulus is more certain than the known annuli.
