In this paper we show that, for each chordal graph G, there is a tree T such that T is a spanning tree of the square G 2 of G and, for every two vertices, the distance between them in T is not larger than the distance in G plus 2. Moreover, we prove that, if G is a strongly chordal graph or even a d

We analyze the approximation ratio of the average distance heuristic for the Steiner tree problem on graphs and prove nearly tight bounds for the cases of complete graphs with binary weights {1, d} or weights in the interval [1, d], where d Β°2. The improvement over other analyzed algorithms is a fac
The distance between a pair of vertices u, u in a graph G is the length of a shortest path joining u and u. The diameter diam(G) of G is the maximum distance between all pairs of vertices in G. A spanning tree Tof G is diameter preserving if diam(T) = diam(G). In this note, we characterize graphs th
## Abstract An application of conservative graphs to topological graph theory is indicated.
## Abstract Coset graphs are a generalization of Cayley graphs. They arise in the construction of graphs and digraphs with transitive automorphism groups. Moreover, the consideration of coset graphs makes it possible to give an algebraic description of regular connected graphs of even degree. In th
A distance-hereditary graph is a connected graph in which every induced path is isometric, i.e., the distance of any two vertices in an induced path equals their distance in the graph. We present a linear time labeling algorithm for the minimum cardinality connected r-dominating set and Steiner tree
