A posteriori Error Bounds for the Zeros of a Polynomial
An algorithm for the computation of error bounds for the zeros of a polynomial is described. This algorithm is derived by applying Rouch6's theorem to a Newton-like interpolation formula for the polynomial, and so it is suitable in the case where the approximations to the zeros of the polynomial are computed successively using deflation. Confluent and clustered approximations are handled easily...

15 صفحه اولOn Annular Bound For The Zeros Of A Polynomial∗
In this paper we present some results on the annular bound for the zeros of a polynomial based on the identities related to the generalized Fibonacci sequence with arbitrary initial condition. Several recently reported results in the same direction are special cases of our results.
متن کاملOn the Improved Family of Simultaneous Methods for the Inclusion of Multiple Polynomial Zeros
Starting from a family of iterative methods for the simultaneous inclusion of multiple complex zeros, we construct efficient iterative methods with accelerated convergence rate by the use of Gauss-Seidel procedure and the suitable corrections. The proposed methods are realized in the circular complex interval arithmetic and produce disks that contain the wanted zeros. The suggested algorithms p...
متن کاملInequalities for the polar derivative of a polynomial with $S$-fold zeros at the origin
Let $p(z)$ be a polynomial of degree $n$ and for a complex number $alpha$, let $D_{alpha}p(z)=np(z)+(alpha-z)p'(z)$ denote the polar derivative of the polynomial p(z) with respect to $alpha$. Dewan et al proved that if $p(z)$ has all its zeros in $|z| leq k, (kleq 1),$ with $s$-fold zeros at the origin then for every $alphainmathbb{C}$ with $|alpha|geq k$, begin{align*} max_{|z|=...
