论文摘要
我们构建了JT重力的各种限制，包括牛顿 - 卡丹和卡洛利亚版本的Dilaton重力在两个维度上以及三维光锥的理论。在BF公式中，我们的边界条件将边界连接与边界标量相关联，作为边界动作，粒子在组歧管上或其某些汉密尔顿还原的粒子作用。在我们的表述中恢复了JT的施瓦茨安，我们表明广告 - rolloll重力产生了扭曲的扭曲边界作用。我们对众多应用和概括发表评论。
We construct various limits of JT gravity, including Newton-Cartan and Carrollian versions of dilaton gravity in two dimensions as well as a theory on the three-dimensional light cone. In the BF formulation our boundary conditions relate boundary connection with boundary scalar, yielding as boundary action the particle action on a group manifold or some Hamiltonian reduction thereof. After recovering in our formulation the Schwarzian for JT, we show that AdS-Carroll gravity yields a twisted warped boundary action. We comment on numerous applications and generalizations.
