本文引入了二维随机Ricci流(SRF)。流关于由Liouville共形场论诱导的一个度量是对称的。利用Dirichlet形式理论,我们构造了平面环面上面积测度的伴随方程在满“$L^1$区域”$\sigma<\sigma_{L^1}=2\srt\pi$中的一个弱解,其中$\sigma$是噪声强度.我们还描述了在一般紧致曲面上SRF所需的主要修改,并列出了一些有待解决的问题。
In this paper we introduce the stochastic Ricci flow (SRF) in two spatial dimensions. The flow is symmetric with respect to a measure induced by Liouville Conformal Field Theory. Using the theory of Dirichlet forms, we construct a weak solution to the associated equation of the area measure on a flat torus, in the full "$L^1$ regime" $\sigma< \sigma_{L^1}=2\sqrt\pi$ where $\sigma$ is the noise strength. We also describe the main necessary modifications needed for the SRF on general compact surfaces, and list some open questions.
