$\mathbb{Z}^d$上临界渗流双臂指数的上界

An upper bound on the two-arms exponent for critical percolation on $\mathbb{Z}^d$

Jacob van den Berg, Diederik van Engelenburg

摘要:

考虑使用$d \geq 2$在$\mathbb{Z}^d$上的临界部位渗流。Cerf(2015)指出,从Aizenman、Kesten和Newman(1987)以及Gandolfi、Grimmett和Russo(1988)的经典工作中,可以得到双臂指数至少为$1/2$。Cerf的论文稍微改进了这个下限。除了$d=2$和高$d$之外,迄今为止在文献中似乎还不知道该指数的上界(甚至不明确)。我们证明了距离- $n$双臂概率至少为$c n^{-(d^2 + 4 d -2)}$($c >0$是一个依赖于$d$的常数),从而给出了上述指数的上界$d^2 + 4 d -2$.

英文摘要:

Consider critical site percolation on $\mathbb{Z}^d$ with $d \geq 2$. Cerf (2015) pointed out that from classical work by Aizenman, Kesten and Newman (1987) and Gandolfi, Grimmett and Russo (1988) one can obtain that the two-arms exponent is at least $1/2$. The paper by Cerf slightly improves that lower bound. Except for $d=2$ and for high $d$, no upper bound for this exponent seems to be known in the literature so far (not even implicity). We show that the distance-$n$ two-arms probability is at least $c n^{-(d^2 + 4 d -2)}$ (with $c >0$ a constant which depends on $d$), thus giving an upper bound $d^2 + 4 d -2$ for the above mentioned exponent.
