标题： Is There Quantum Gravity in Two Dimensions?

摘要： 引入了一种可以在这两种方法之间进行插值的混合模型，即（原始的）Regge 方法和动力学三角剖分方法。通过在测度上获得的灵活性来研究固定几何中的动力学三角剖分。我们的数值结果支持 KPZ 指数。接着是对二维情况下似乎缺乏引力效应这一现象进行了批判性评估。 显示英文摘要

摘要： A hybrid model which allows to interpolate between the (original) Regge approach and dynamical triangulations is introduced. The gained flexibility in the measure is exploited to study dynamical triangulation in a fixed geometry. Our numerical results support KPZ exponents. A critical assessment concerning the apparent lack of gravitational effects in two dimensions follows.
