从引力的仿射规范理论到正交规范理论的拓扑约化

On the topological reduction from the affine to the orthogonal gauge theory of gravity

R. F. Sobreiro, V. J. Vasquez Otoya

摘要:

利用纤维丛理论描述引力的度规-仿射规范理论,我们能够证明度规-仿射规范理论可以约化为Riemann-Cartan规范理论。我们为简化几何所付出的代价是,与原始设置的非度规自由度相关的物质场的存在。此外,一个可能的框架,建设一个量子引力理论的发展沿文本。

英文摘要:

Making use of the fibre bundle theory to describe metric-affine gauge theories of gravity we are able to show that metric-affine gauge theory can be reduced to the Riemann-Cartan one. The price we pay for simplifying the geometry is the presence of matter fields associated with the nonmetric degrees of freedom of the original setup. Also, a possible framework for the construction of a quantum gravity theory is developed along the text.
