设${\cal G}$是一棵度为n_0 +1$的齐次树上的初始无限簇(IIC)。我们得到的连续时间简单随机游走$Y$上${\cal G}$的转移密度的估计,该过程满足反常扩散,并具有谱维数4/3。
Let ${\cal G}$ be the incipient infinite cluster (IIC) for percolation on a homogeneous tree of degree $n_0+1$. We obtain estimates for the transition density of the continuous time simple random walk $Y$ on ${\cal G}$; the process satisfies anomalous diffusion and has spectral dimension 4/3.
