摘要

SINCE there are many difficulties in finding a single ropt of a polynomial, it becomes more and more important for parallel iterations to determine all roots simultaneously. Among the proposed methods, the iterative family produced by paralleling theiterative family of Halley using Bell's polynomial appears the most systematic and richest, In fact the paper becomes the main contents of the monograph. However, we know that the special feature that the parallel iterations of simultaneously finding allroots of a polynomial depend on the evaluations of the derivatives of / prevents its application in the computation of eigenvalue problems because the evaluations of the derivative of f are difficult in this case, Even though the function f is given bythe explicit formulation, the case is also the same.
