Abstract:A molecular graph or a chemical graph is a simple graph related to the structure of a chemical compound. In this paper, we introduce the general fifth M-Zagreb indices and fifth M3-Zagreb index and their polynomials of a molecular graph. Also we compute the general fifth M-Zagreb indices and fifth M3-Zagreb index of PAMAM dendrimer graphs. Finally, we compute the fifth M3-Zagreb polynomial of PAMAM dendrimer graphs.
“…Recently, some augmented indices were studied, for example, in [7,8,9,10,11,12,13,14]. The domination degree d du [15] of a vertex u in a graph G is defined as the number of minimal dominating sets of G which contains u.…”
In this study, we introduce the domination augmented Banhatti index, domination augmented Banhatti sum index and their corresponding polynomials of a graph. We compute these newly defined domination augmented Banhatti indices for some importantchemical drugs such as chloroquine and hydroxychloroquine which are appeared in medical science

“…In particular, in [11], the authors considered two infinite classes NS1[n] and NS2[n] of nanostar dendrimers and computed the Zagreb indices and Zagreb polynomials for these special nanostar dendrimers. In [12], the author determined certain Zagreb polynomials of a special type of dendrimer nanostar D 3 [n], and the Zagreb indices and Zagreb polynomials of the same dendrimer nanostars were computed in [13]. The computation of some fifth multiplicative Zagreb indices of PAMAMdendrimers was reported in [14].…”
The association of M-polynomial to chemical compounds and chemical networks is a relatively new idea, and it gives good results about the topological indices. These results are then used to correlate the chemical compounds and chemical networks with their chemical properties and bioactivities. In this paper, an effort is made to compute the general form of the M-polynomials for two classes of dendrimer nanostars and four types of nanotubes. These nanotubes have very nice symmetries in their structural representations, which have been used to determine the corresponding M-polynomials. Furthermore, by using the general form of M-polynomial of these nanostructures, some degree-based topological indices have been computed. In the end, the graphical representation of the M-polynomials is shown, and a detailed comparison between the obtained topological indices for aforementioned chemical structures is discussed.
“…Recently some multiplicative atom bond connectivity indices were studied, for example, in [16,17,18,9,20,21,22,23,24,25,26,27]. Now we define the multiplicative neighborhood sum atom bond connectivity index as…”
In this paper, we introduce the neighborhood sum atom bond connectivity index and the multiplicative neighborhood sum atom bond connectivity index of a graph. Also we compute these indices for certain dendrimers
