摘要：

We investigate the loop equations for 2D quantum gravity + matter with running central charge D. The matter field is constructed as an SOS model with floating electric charge alpha-0. We find the one-loop amplitudes for different boundary conditions and conjecture a compact formula for multiloop correlators. Finally, we discuss the limit D --> 1 (alpha-0 --> 0) and the origin of the scaling violation at D = 1.
