摘要

我们考虑了与长程渗流截断问题有关的一些问题。给出了某些长程定向债券是开放的概率；假设这些概率是不可求和的，当我们截断图时，我们会问渗流的概率是否为正，不允许范围超过可能很大但有限的阈值的键。如果顶点集为$\Z^2$，则此问题仍然存在。我们给出了一些答案是肯定的条件。其中一个结果推广了[Alves，Hilario，de Lima，Valesin，Journ.Stat.Phys.｛\bf 122｝，972（2017）]中的先前结果。

Truncation of long-range percolation models with square non-summable interactions

We consider some problems related to the truncation question in long-range percolation. It is given probabilities that certain long-range oriented bonds are open; assuming that this probabilities are not summable, we ask if the probability of percolation is positive when we truncate the graph, disallowing bonds of range above a possibly large but finite threshold. This question is still open if the set of vertices is $\Z^2$. We give some conditions in which the answer is affirmative. One of these results generalize the previous result in [Alves, Hilario, de Lima, Valesin, Journ. Stat. Phys. {\bf 122}, 972 (2017)].
