Abstract

Let C k denote the graph with vertices (e{open} 1, ..., e{open} k ), e{open} i =0,1 and vertices adjacent if they differ in exactly one coordinate. We call C k the k-cube. Let G=G k, p denote the random subgraph of C k defined by letting {Mathematical expression} for all i, j ∈ C k and letting these probabilities be mutually independent. We show that for p=λ/k, λ>1, G k, p almost surely contains a connected component of size c2 k, c=c(λ). It is also true that the second largest component is of size o(2 k ).
