| Authors: | Fangyu Sun Peter Kosmol |
| Abstract: | Starting from disjoint disks which contain polynomial complex zeros, the new iterative interval method for simultaneous finding of inclusive disks for complex zeros is formulated. The convergence theorem and the conditions for convergence are considered, and the convergence is shown to be fourth. Numerical examples are included. |
| Keywords: | Iterative method Interval arithmetic Zeros of polynomial Lagrange interpolation Order of convergence |
