论文摘要
我们构建了一个遗传学随机矩阵模型，该模型提供了Cangemi-Jackiw（CJ）重力的稳定的非扰动完成，这是平坦的二维理论。矩阵模型将拓扑扩展中的所有顺序复制，CJ重力的欧几里得分区功能具有任意数量的边界。非扰动完成可以在平面量子重力中进行可观察到的确切计算，我们用来明确表征Bondi Hamiltonian Spectrum。我们讨论了结果对平面S-Matrix和黑洞的含义。
We construct a Hermitian random matrix model that provides a stable non-perturbative completion of Cangemi-Jackiw (CJ) gravity, a two-dimensional theory of flat spacetimes. The matrix model reproduces, to all orders in the topological expansion, the Euclidean partition function of CJ gravity with an arbitrary number of boundaries. The non-perturbative completion enables the exact computation of observables in flat space quantum gravity which we use to explicitly characterize the Bondi Hamiltonian spectrum. We discuss the implications of our results for the flat space S-matrix and black holes.
