| Outline of Final Research Achievements |
We have studied the spectrum and the resonance of Dirac operators, especially (1) the spectral concentration and the non-relativistic limit for potentials infinite at infinity, (2) the spectral structure of many-body Dirac operators, (3) the non-existence of zero eigenvalue for the massless case. We could give our some results for these problems by the corabolation with Hiroshi Ito of Ehime University for (1) and with Takshi Okaji of Kyoto University and Hubert Kalf of Munich University for (2), (3).
