论文摘要
我们表明，最近提出的针对三维非相关性重力的行动可以通过占据相对论的拉格朗日式的限制来获得，该行为涉及涉及共同繁星限制的庞加雷代数。我们指出，我们的结构相似之处与三维的Galilei重力和扩展的Bargmann重力可以通过占据相对论Lagrangian的限制来获得，该限制涉及Poincare代数。我们将结果扩展到ADS案例，我们将看到相对论和非相对论水平上都有手性分解。我们评论可能的进一步概括。
We show that a recently proposed action for three-dimensional non-relativistic gravity can be obtained by taking the limit of a relativistic Lagrangian that involves the co-adjoint Poincare algebra. We point out the similarity of our construction with the way that three-dimensional Galilei Gravity and Extended Bargmann Gravity can be obtained by taking the limit of a relativistic Lagrangian that involves the Poincare algebra. We extend our results to the AdS case and we will see that there is a chiral decomposition both at the relativistic and non-relativistic level. We comment on possible further generalizations.
