The results in this paper are important for our construction of global algorithms based on Newton’s method, and for estimation of the efficiency of those algorithms. The idea is simply to apply the theorems here to a finite sequence of equations of the form \(f(z)-t_ if(z_ 0)=0\), \(0\leq t_ i\leq 1\), to solve \(f(z)=0\).
