Witrynathe projector onto its eigenspace and Q the orthogonal projector to P. We have P+Q= I and PQ= 0. Now clearly PMP= λP. M = (P+ Q)M(P+ Q) = PMP+ QMQ+ QMP+ PMQ. Now QMP = 0 and (PMQ)† = QMP = 0 so PMQ= 0. Also QMQis hermitian so by in-ductive hypothesis it has the required form and from M= λP+ QMQ we conclude. 11 Witryna11 wrz 2024 · Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of …
