The average lower connectivity denoted by kappa(av)(G) is the value (Sigma(v epsilon V(G))s(v)(G))/vertical bar V(G)vertical bar. It is shown that this parameter can be used to measure the vulnerability of networks. This paper contains results on bounds for the average lower connectivity and obtains the average lower connectivity of some graphs.EnglishArticle
