The incipient infinite cluster in two-dimensional percolation

  • Harry Kesten


LetP p be the probability measure on the configurations of occupied and vacant vertices of a two-dimensional graphG, under which all vertices are independently occupied (respectively vacant) with probabilityp (respectively 1-p). LetP H be the critical probability for this system andW the occupied cluster of some fixed vertexw0. We show that for many graphsG, such as\(\mathbb{Z}^2 \), or its covering graph (which corresponds to bond percolation on\(\mathbb{Z}^2 \)), the following two conditional probability measures converge and have the same limit,v say:

  1. i)

    P pH {·∣w0 is connected by an occupied path to the boundary of the square [-n,n]2} asn→∞,

  2. ii)

    P p {·∣W is infinite} aspp H .


On a set ofv-measure one,w0 belongs to a unique infinite occupied cluster,WW} say. We propose thatWW} be used for the “incipient infinite cluster”. Some properties of the density ofWW} and its “backbone” are derived.
