摘要
The paper deals with normal operators R and S satisfying simple commutation relations that we encounter investigating the quantum deformation of the E(2) group. We show that R + S admits a normal extension if and only if R-1S satisfies a certain spectral condition. A number of related formulae are derived. In particular, all the functions f satisfying the character equation f(R + S) = f(R)f(S) are found.
