We measure the fractal dimension of loop-erased random walk (LERW) in three dimensions and estimate that it is 1.624 00 ± 0.000 05. LERW is closely related to the uniform spanning tree and the Abelian sandpile model. We simulated LERW on both the cubic and face-centered-cubic lattices; the corrections to scaling are slightly smaller for the face-centered-cubic lattice.
我们测量了三维中环路擦除随机游走(LERW)的分形维数,并估计其为1.624 00±0.000 05。LERW与均匀生成树和阿贝尔沙堆模型密切相关。我们在立方晶格和面心立方晶格上模拟了LERW;面心立方晶格的标度修正略小。
