论文摘要
我们表明，最小的大规模3D重力（MMG）以及拓扑大量重力，是更笼统的“最小质量重力”理论（具有单一的巨大传播模式）的特定情况，这是由于基于hietarinta或Maxwell exwell eggebra的Chern-Simons自发性破坏而产生的。与MMG情况类似，传播大量模式既不是tachyon也不是幽灵的要求，并且与边界CFT相关的渐近代数的中心电荷是正面的，对理论参数范围施加了限制。
We show that minimal massive 3d gravity (MMG), as well as the topological massive gravity, are particular cases of a more general `minimal massive gravity' theory (with a single massive propagating mode) arising upon spontaneous breaking of a local symmetry in a Chern-Simons gravity based on a Hietarinta or Maxwell algebra. Similar to the MMG case, the requirements that the propagating massive mode is neither tachyon nor ghost and that the central charges of an asymptotic algebra associated with a boundary CFT are positive, impose restrictions on the range of the parameters of the theory.
