We discuss about the Hermitian treatment of Dyson-type boson expansiontheory. We show that the basic assumption of the conventional treatment doesnot hold in general and the method is only approximately valid. We also showthat the approximation is the same order as that of truncation of the expansionusually done in the Hermitian type boson expansion theory.Comment: 18 page, no figur
