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 stru

In this paper we present a method for analyzing a general class of random

. 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 bounds on their mixing rates, i.e., the number of steps required to ลฝ . guarantee that the resulting distribution is close to the uniform stationary distribution.

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
We consider two types of random subgraphs of the n-cube. For these models we study the asymptotic behaviour of the number of d-cubes when d = 1,2,
