Lehrbuch der Mathematischen Physik: Band 3: Quantenmechanik von Atomen und Molekülen

In der Quantentheorie werden Observable durch Operatoren im Hilbert-Raum dargestellt. Der dafür geeignete mathematische Rahmen sind die Cx - Algebren, welche Matrizen und komplexe Funktionen verallgemeinern. Allerdings benötigt guy in der Physik auch unbeschränkte Operatoren, deren Problematik eigens untersucht werden muß.
