چکیده
|
The 2-degree of a vertex v in a (molecular) graph g is the number of vertices which are at distance two from v in g. the f-leap index of a molecular graph g is the sum of cubes of the 2-degree of every vertex v in g. in this research study, we have computed the f-leap index of some special classes of bridges and chain graphs. we also have determined the f-leap index of some chemical structures including polyphenyl chains and spiro chains.
