JOURNAL NAME: Advances in Pure Mathematics, Vol.3 No.1, January 29, 2013
ABSTRACT: A class of meta-invariant operators over Cayley-Dickson algebra is studied. Their spectral theory is investigated. More- over, theorems about spectra of generalized unitary operators and their semigroups are demonstrated.
