Mathematical Logic Quarterly 57 (5):481-484 (2011)

In this paper, we show that Ogasawa’s theorem has a proof in Bishop style constructive mathematics . In 25, we introduced the elementary constructive theory of C*-algebras in BISH, but we did not discuss the powers of positive elements there. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
