Centrality measures the status of a vertex in a graph. Centrality betweenness determines how often a vertex comes in between pairs of other vertices. Since shortest paths are considered here, the centrality betweenness of a vertex is proportional to the number of shortest paths passing through it. Join is an important graph operation which interconnects two graphs. The centrality betweenness of some derived graphs generated by this operation is presented here.

Abstract


Centrality measures the status of a vertex in a graph. Centrality betweenness determines how often a vertex comes in between pairs of other vertices. Since shortest paths are considered here, the centrality betweenness of a vertex is proportional to the number of shortest paths passing through it. Join is an important graph operation which interconnects two graphs. The centrality betweenness of some derived graphs generated by this operation is presented here.
