WebSpanning Trees. Spanning trees are special subgraphs of a graph that have several important properties. First, if T is a spanning tree of graph G, then T must span G, meaning T must contain every vertex in G. Second, T must be a subgraph of G. In other words, every edge that is in T must also appear in G. Third, if every edge in T also exists ... http://scholar.sjp.ac.lk/lanel/publications
