Let G(n, p ) denote the probability space consisting of all spanning subgraphs g of the n-cube En, and the probability is defined as ERDOS and SPENCER investigated the connectedness of such random graphs for fixed probability p , O<p<l (cf. [l]). I n this paper we study coverings of the vertex set

โฆ Synopsis
The N-cube is a graph with 2 N vertices and N 2 Ny1 edges. Suppose indepen- dent uniform random edge weights are assigned and let T be the spanning tree of minimal ลฝ .
y 1 N ฯฑ y3 total weight. Then the weight of T is asymptotic to N 2 ร i as N ยช ฯฑ. Asymp-is1 totics are also given for the local structure of T and for the distribution of its kth largest edge weight, k fixed.

In this paper we present a method for analyzing a general class of random ## ลฝ . walks on the n-cube and certain subgraphs of it . These walks all have the property that the transition probabilities depend only on the level of the point at which the walk is. For these walks, we derive sharp bound
