三维高次导数引力和四维临界性的完全分类

A Complete Classification of Higher Derivative Gravity in 3D and Criticality in 4D

Nobuyoshi Ohta

摘要:

我们在具有最一般的二次曲率、Lorentz-Chern-Simons和宇宙学项的三维引力场中研究了该理论是么正的和稳定的条件。我们提供了围绕平坦闵可夫斯基和(反)德西特时空的酉理论的完整分类。分析是通过检查这些经典真空周围的二次波动。我们还讨论了如何在拉格朗日水平上理解四维理论的临界条件。

英文摘要:

We study the condition that the theory is unitary and stable in three-dimensional gravity with most general quadratic curvature, Lorentz-Chern-Simons and cosmological terms. We provide the complete classification of the unitary theories around flat Minkowski and (anti-)de Sitter spacetimes. The analysis is performed by examining the quadratic fluctuations around these classical vacua. We also discuss how to understand critical condition for four-dimensional theories at the Lagrangian level.
