1. The oscillator group. The one-dimensional oscillator group was studied by Streater (7) when he was comparing different methods of calculating representations. It is interesting to generalize this work and consider the group corresponding to the n-dimensional anisotropic oscillator with frequencies ωj In fact, the ideas can be generalized to even larger groups and, in the process of considering their representa tions, several points emerge connected with the harmonic oscillator degeneracies.
