Journal ArticleDOI
An improved interval Newton operator
R. Krawczyk,Arnold Neumaier +1 more
TL;DR: In this paper, interval operators producing a sequence of intervals are discussed, each interval of such a sequence encloses a set of solutions of nonlinear systems of equations, and theorems about existence and uniqueness of fixintervals are formulated.
Journal ArticleDOI
Interval extensions and interval iterations
TL;DR: Methods for interval iteration to include a solution of an operator equation is obtained by transforming the equation in iterative form a parameter is chosen appropriately, so that the convergence of the interval sequence becomes as fast as possible.
Journal ArticleDOI
A globally convergent ball newton method
TL;DR: In this paper, a new n-dimensional Newton method is presented, which is globally convergent and requires only a finite number of steps to find the desired zero of the given function.
Journal ArticleDOI
Über Simultanverfahren zur Bestimmung reeller Polynomwurzeln
Götz Alefeld,Jürgen Herzberger +1 more
TL;DR: In this article, a single-step and a total-step method for computing all roots of a polynomial simultaneously is presented, in which all roots are simple and real and if one known disjunct interval is contained, both methods are always convergent.
Journal ArticleDOI
Nullstelleneinschlieβung mit dem Newton-Verfahren ohne Invertierung von Intervallmatrizen
Götz Alefeld,J. Herzberger +1 more
TL;DR: In this paper, a modification converging superlinear, without the necessity of inverting matrices, is presented, and two numerical examples are given; see Section 2.1.
