Abstract

Interval operatorsF for constructing inclusion monotone interval sequences by iteration methods are discussed. IfX 1X 0 andX k+1 :=F(X k ,k=0,1,…, then for two types of operators—aK-and anN-operator-it can be proved thatX k+1 X k for allk. Also the speed of convergence of the interval sequence will be explored.

Zusammenfassung

IntervalloperatorenF werden diskutiert, mit deren Hilfe man durch Iteration eine inklusionsmonotone Intervallfolge erzeugen kann. Für zwei Typen von Intervalloperatoren —K- undN-Operator-kann bewiesen werden, daßX 1X 0 undX k+1 :=F(X k ),k=0,1,…,X k+1 X k für allek impliziert. Es wird auch die Konvergenzgeschwindigkeit der Intervallfolgen untersucht.
