Quasi-permutable normal operators in octonion Hilbert spaces and spectra
arXiv:1204.2571 · doi:10.1007/s00006-013-0430-4
Abstract
Families of quasi-permutable normal operators in octonion Hilbert spaces are investigated. Their spectra are studied. Multiparameter semigroups of such operators are considered. A non-associative analog of Stone's theorem is proved.
