WebAbstract. Let T be a tree and consider the Randić index χ ( T )=∑ _ {vi - vj} (1/\sqrt {\delta (v_i )\delta (v_j )} ) ), where v i – v j runs over all edges of T and δ ( v i ) denotes the degree of the vertex v i . Using counting arguments we show that the Randić index, is monotone increasing over the well (lexicographic order) ordered ...
