If they form a commuting square, then we have H(MIN) = H(MjMnN). If their commutants form a commuting square, then we have H(MIN) = H(M V NIN).Department of Mathematics, Hokkaido UniversityDepartmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/68911info:doi/10.14943/83309https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/68911/1/pre165.pdfHokkaido University Preprint Series in Mathematics1651181992-10engpublisher
