چکیده

Let g=(v, e) is a molecular graph in which the vertex set v represents atoms and the edge set e represents the bonds between the atoms, corresponding to a chemical compound. in this research study, we introduced a new type of distance based topological indices called multiplicative leap zagreb indices which is used to analyze the structural properties of some chemicals. they are as follows , l ii1(g)=ii-u∋v(g) d2(u)^2,lii2(g)=ii-uv∋e(g) d2(u)d2(v) and lii(g)=ii-u∋v(g) deg (u)d2 (u) where d2(u) is the 2-degree of the vertex u, defined as the number of vertices which are at distance two from u in g. we computed exact values of these indices for some well known graphs and also we obtained results for a special families of tthorny graphs namely, tthorny path graphs, tthorny star graphs, tthorny complete graphs and tthorny complete bipartite graphs and tthorny cycles.
