ATOM BOND-CONNECTIVITY ENERGY OF A GRAPH
The purpose of this paper is to introduce and investigate the atom bond-connectivity energy ABCE(G) of a graph G. We present some upper and lower bounds for ABCE(G) and calculate it for several graph classes and also for some graphs with one edge deleted which enables us to calculate this index for...

description | The purpose of this paper is to introduce and investigate the atom bond-connectivity energy ABCE(G) of a graph G. We present some upper and lower bounds for ABCE(G) and calculate it for several graph classes and also for some graphs with one edge deleted which enables us to calculate this index for larger graphs by means of smaller graphs. Also ABCE(G) is calculated for some complements of several graphs.. Keywords: Atom bond-connectivity matrix, atom bond-connectivity energy, atom bond-connectivity characteristic polynomial, k-complement, k(i)-complement. AMS Subject Classification: 05C50 |
