    Es sei \(H\) ein Hilbertscher Raum, \(K\) ein Boolescher Körper von Mannigfaltigkeiten in \(H\) (d. h., wenn \(a\), \(b\in K\), dann \(H- a \in K\) und \(a+b\in K\), und, wenn \(a\cdot b = 0\), dann \(a\perp b\)). \(K\) heißt vollkommen, falls er vollständig additiv ist. Verf. beweist, daß es immer möglich ist, einen Körper in einen vollkommenen Oberkörper einzubetten.
