【 摘 要 】
Consider the class of k-independent bond or site percolations with parameter p on a tree T. We derive tight bounds on p for both almost sure percolation and almost sure nonpercolation. The bounds are continuous functions of k and the branching number of T. This extends previous results by Lyons for the independent case (k = 0) and by Balister & Bollobas for 1-independent bond percolations. Central to our argumentation are moment method bounds a la Lyons supplemented by explicit percolation models a la Balister & Bollobas. An indispensable tool is the mini mality and explicit construction of Shearer's measure on the k-fuzz of Z. (C) 2011 Published by Elsevier B.V.
