We study a uniform model SG(n,d) for random interval graphs on the uni
t interval. We derive exact results and limit theorems for the distrib
ution of random variables related to the connectivity of this random i
nterval graph. While having the same threshold function for some prope
rties like the Poisson approximation for the number of isolated vertic
es, our results show that the standard binomial model G(n,p) of random
graphs and SG(n,d) differ in many aspects. (C) 1996 John Wiley & Sons
