COMPUTING TWO OF GEOMETRIC-ARTHIMETIC INDICES OF SOME GRAPHS

The concept of geometric–arithmetic index was introduced in the chemical graph theory recently. Also the edge version of geometric–arithmetic index of graphs is introduced based on the end-vertex degrees of edges of their line graphs. In this paper, we compute this index for PAHn, CAk (C6) and Polyomino Chain.
