共形联络动力学的位形空间

The Configuration Space of Conformal Connection-Dynamics

James A. Reid, Charles H. -T. Wang

摘要:

量子引力的约化哈密顿公式的位形空间已经被证明,对于非里奇平坦度规,是黎曼曲面上共形结构的泰希米勒空间的高维模拟。在这篇文章中,我们证明了共形连接动力学的位形空间自然是一个高维的Teichmüller空间,服从相同的条件。这个结果的一个直接结果是,圈量子引力的Barbero-Immirzi参数在所有共形正则引力理论中自然地呈现出一个量子特征。

英文摘要:

The configuration space of the reduced Hamiltonian formulation of quantum gravity has been shown, for non-Ricci flat metrics, to be a higher-dimensional analogue of the Teichmüller space of conformal structures on a Riemann surface. In this article we show that the configuration space of conformal connection-dynamics is naturally a higher-dimensional Teichmüller space, subject to the same condition. An immediate consequence of this result is that the Barbero-Immirzi parameter of loop quantum gravity naturally assumes a dilatonic character in all conformal canonical gravity theories.
