International Journal of Quantum ChemistryOn the unitarily invariant decomposition of Hermitian operatorsChia‐Chung Sun, Xue‐Qui Li, Auchin TangPublished Jun 1, 1984• 7 citationsPublisherAbstractAbstract The unitarily invariant decomposition of Hermitian operators for a boson system is performed by means of the symmetry of group SO(2, 1) and the decomposition is also closely related with Lie algebra.DOI10.1002/qua.560250609
