| Research Abstract |
A kind of spectral theory of q-deformed operators in a Hilbert space is needed so that unbounded representations of quantum algebras are analyzed. This work is devoted toinvestigating a q-normal operator in a Hilbert space, compared with a standard spectral measure and the spectral decomposition for a normal operator in a Hilbertspace. It is shown that, if a positive number q is smaller than 1, every q-normal operator in a Hilbert space is extended to a standard normal operator in a possibly larger Hilbert space.
