Abstract

Let G be a kG-edge connected graph and Dc(G) denote the diameter of G after deleting any of its c kG edges. We prove that if G1, G2, . . . , Gq are k1-edge connected, k2-edge connected,. . . , kq-edge connected graphs and 0 ≤ a1 k1, 0 ≤ a2 k2,. . . , 0 ≤ aq kq and a = a1 + a2 + . . . + aq + (q - 1), then the edge fault-diameter of G, the Cartesian product of G1, G2, . . . , Gq, with a faulty edges is Da(G) ≤ Da1(G1) + Da2(G2) + . . . + Daq(Gq) + 1.
