✦ Synopsis


Because of their good properties, iterated line digraphs (specially Kautz and de Bruijn digraphs) have been considered to design interconnection networks. The diameter-vulnerability of a digraph is the maximum diameter of the subdigraphs obtained by deleting a fixed number of vertices or arcs. For any digraph G, we find a constant C (not greater than twice the diameter of G) such that, under certain conditions, the diameter vulnerability of the iterated line digraph LkG is at most the diameter of LkG plus C. The results in this paper generalize previous results on the diameter-vulnerability of particular families of iterated line digraphs (Kautz and de Bruijn digraphs).

We show that in the Kautz digraph K(d, t) with d' + d'-1 vertices each having out degree d, there exist d vertex-disjoint paths between any pair of distinct vertices, one of length at most t, d -2 of length at most t + 1, and one of length at most t + 2.

## Abstract We prove that every __r__‐biregular digraph with __n__ vertices has its directed diamter bounded by (3__n__ ‐ __r__ ‐ 3)/(__r__ +1). We show that this bound is tight for directed as well as for undirected graphs. The upper bound remains valid for Eulerian digraphs with minimum outdegree

For a connected graph H of order at least 3, the H-line graph HL(G) of a graph G is defined as that graph whose vertices are the edges of G and where two vertices of HL(G) are adjacent if and only if the corresponding edges of G are adjacent and belong to a common copy of H. For k >~ 2, the kth ite
