Abstract
Numerical invariants or topological indices (TIs) are the graph descriptors that assist us in preserving physicochemical characteristics like boiling point, temperature, pressure, melting point, freezing point, and stability of different chemical compounds. To evaluate the physical and chemical properties of molecules, numerous TIs have been studied in the literature. Among all the investigated indices in the literature, the Zagreb connection indices (ZCIs) are examined to be more valuable to evaluate the chemical and physical attributes of molecular substances. In this thesis, we calculate ZCIs, known as first ZCI (FsZCI), second ZCI (SZCI), modified FsZCI, modified SZCI, and modified third ZCI (TZCI). Moreover, we compute multiplicative ZCI (MZCI), named as first MZCI (FsMZCI), second MZCI (SMZCI), third MZCI (TMZCI), fourth MZCI (FrMZCI), modified FsMZCI, modified SMZCI, and modified TMZCI of dendrimer nanostars. Moreover, we compare our computed results with each other to check their authenticity and superiority.
