| چکیده | ||
| A molecular graph is hydrogen depleted chemical structure in which vertices denote atoms and edges denote the bonds. Nanostar dendrimers, a type of chemical compound, have potential in fields such as chemistry, nanotechnology, electronics, optics, materials science and architecture. Nanostar dendrimers and their molecular descriptors are being widely used in QSAR/QSPR and these are studies in chemistry and drugj designing as well as modeling of compounds. There are certain types of topological indices like distance based, degree based and counting related topological indices. In this article we gave exacts relations for first and second Zagrebs index, hyper Zagreb index, multiplicative Zagreb indices ass well as first and second Zagreb polynomials for some families of nanostar dendrimers. | ||
