Abstract

A class of interval-Newton-operatorsN a will be discussed. One of them,Ň, is optimal in the manner thatŇ(X)⊑N a (X). With the help of such an interval operator we can given an existence theorem for the solution x* of the equationg(x)=0.

Zusammenfassung

Eine Klasse von IntervalloperatorenN a wird diskutiert. Einer von ihnen —Ň — ist optimal in dem Sinne, daßŇ(X)⊑N a (X) gilt. Mit Hilfe eines solchen Intervalloperators kann die Existenz einer Lösungx * einer Gleichungg(x)=0 bewiesen werden.
