具体内容

稿件研究以生成树数目为权抽样的平面图上的平稳随机游走。作者声称该游走收敛到单位面积√2-Liouville量子球面上的Liouville布朗运动,且收敛同时保留条件路径律与带测度度量空间。游走在所有关联半边上均匀选择,从平稳度测度出发;在总尝试率为1、连续Dirichlet型含因子1/2时,时间加速恰为图的边数。证明依赖同一系综的轮廓与度量极限。

英文原始摘要

We prove that stationary random walk on a planar map sampled with weight equal to its number of spanning trees converges to Liouville Brownian motion on the unit-area $`\sqrt2`$-Liouville quantum sphere. The convergence retains the conditional path law jointly with the measured metric space. The walk chooses uniformly among all incident half-edges and starts from the stationary degree measure. For total attempt rate one and the continuum Dirichlet form with factor 1/2, the time acceleration is exactly the number of map edges. The result uses the companion contour and metric limits for this same ensemble.
