| 英文摘要 | The disclination in Lorentz spacetime is studied in detail by means of topological properties of phi -mapping. It is found that the spacetime disclination can be described in terms of a Dirac spinor. The size of the disclination, which is proved to be the difference of two sets of su(2)-like monopoles expressed by two mixed spinors, is quantized topologically in terms of topological invariants winding number. The projection of spacetime disclination density along an antisymmetric tensor field is characterized by the Brouwer degree and Hopf index. |
