Abstract
In non-relativistic systems, when there is spontaneous symmetry breaking, the number of Nambu-Goldstone bosons () are not necessarily equal to the number of broken generators (). Here we use the method of operators for analyzing the necessary conditions in order to obtain the correct dispersion relation for the Nambu-Goldstone bosons.
