Abstract

In this paper an improved Moore test for the coupled system:f(x, y)=0,g(x, y)=0 is described: x+ is calculated from x and y in a forward-substep, and we use x+ and y to compute y+ in a backward-substep. It is shown that, if x+ ⊂ x, y+ ⊂ y, then a solution of the coupled system (x*,y*) ∈ (x+, y+) exists. On this foundation, we prove convergence of a point iterative algorithm for solving coupled systems.

Zusammenfassung

In der vorliegenden Arbeit wird ein veränderter Moore-Test für gekoppelte Gleichungssystemef(x, y)=0,g(x, y)=0 beschrieben, darin wird x+ aus x und y in einem Vorwärtsschritt berechnet, und y+ aus x+ und y in einem Rückwärtsschritt berechnet. Es wird gezeigt, daß eine Lösung der gekoppelten Systeme (x*,y*) ∈ (x+, y+) existiert, wenn x+ ⊂ x, y+ ⊂ y. Auf dieser Grundlage stellen wir ein Punktiterationsverfahren zur Lösung der gekoppelten Systeme vor, und ein Konvergenzsatz wird angegeben.
