• SECOND ZAGREB-K-BANHATTI INDEX OF A GRAPH

V. R. KULLI*

Abstract


The K-Banhatti indices were introduced by Kulli in 2016. The Zagreb indices were proposed by Gutman and Trinajstić in 1972. The Zagreb indices and K-Banhatti indices are closely related. In this paper, we establish some relations between Zagreb, K-Banhatti and second Zagreb-K-Banhatti indices. Also we obtain lower and upper bounds for the second Zagreb-K-Banhatti index of a graph in terms of Zagreb and K-Banhatti indices.


Keywords
