Extremal decomposition of Wightman functions and of states on nuclear*-algebras by Choquet theory

Description

We give a short proof for the decomposability of states on nuclear *-algebras into extremal states by using the integral decompositions of Choquet and the nuclear spectral theorem, recovering a recent result by Borchers and Yngvason. The decomposition of Wightman fields into irreducible fields is a special case of this. We also indicate a quick solution of the moment problem on nuclear spaces. (orig.)

Abstract (German)

Wir beweisen die Zerlegbarkeit von Zustaenden auf nuklearen *-Algebras in Extremzustaenden mit den Integralzerlegungen von Choquet und dem nuklearen Spektraltheorem unter Einbeziehung eines von Borchers und Yngvason mitgeteilten Ergebnisses. Die Zerlegung von Wightmanfeldern in irreduzible Felder ist ein Sonderfall. Wir beschreiben ferner eine rasche Loesung des Momentenproblems im nuklearen Raum. (orig./AK)
