我们展示了如何牛顿引力的牛顿-嘉当公式可以从巴格曼代数,即中心扩展的伽利略代数的测量。在这个测量过程中,施加了几个曲率约束。这些将代数的空间(时间)平移对称性转换为空间(时间)一般坐标变换,并使自旋连接规范场相关。此外,我们需要两个独立的vielbein假设的时间和空间方向。在最后一步中,我们施加一个额外的曲率约束,以建立与(在壳)牛顿-Cartan理论的联系。我们讨论了一些扩展我们的工作是相关的上下文中的AdS-CFT通信。
We show how the Newton-Cartan formulation of Newtonian gravity can be obtained from gauging the Bargmann algebra, i.e. the centrally extended Galilean algebra. In this gauging procedure several curvature constraints are imposed. These convert the spatial (time) translational symmetries of the algebra into spatial (time) general coordinate transformations and make the spin connection gauge fields dependent. In addition we require two independent vielbein postulates for the temporal and spatial directions. In the final step we impose an additional curvature constraint to establish the connection with the (on-shell) Newton-Cartan theory. We discuss a few extensions of our work that are relevant in the context of the AdS-CFT correspondence.
