| 摘 要： | 研究了有挠时空的引力量子化问题，获得了一次型有挠引力的Ｗｈｅｅｌｅｒ－Ｄｅｗｉｔｔ方程，超空间的号差是洛仑兹的。在小超空间近似下，如果宇宙波函数是正规的，或者取无边界边界条件，都得出均匀各向同性量子宇宙以无挠方式演化的结论。

| Abstract: | The quantization problems of gravity with torsion are discussed and the influence of torsion to the evolution of universe is studied. When matter fields are absent, Wheeler-Dewitt equation of gravity with torsion of type R is obtained, the metric of the superspace has Lorentzian signature. Quantum cosmology with torsion has been studied under minisuperspace approximation, and it is proved that torsion has no contribution to the evolution of universe if the regularity condition of the wave function or no boundary proposal has to be satisfied. |
