| Résumé : | The most general first-order differential operator that commutes with the Dirac operator and hence permits the construction of quantum numbers is given. Necessary and sufficient conditions for its existence are expressed in terms of the generalized Killing tensors of Yano. As a special case we obtain an extension to curved space-time of a covariant description of spin. © 1979 The American Physical Society. |
