The Wiener and Zagreb indices of conjugacy class graph of the dihedral groups
Topological indices are numerical values that can be analysed to predict the chemical properties of the molecular structure which are computed for a graph related to groups.

| Summary: | Topological indices are numerical values that can be analysed to predict the chemical properties of the molecular structure which are computed for a graph related to groups. Meanwhile, the conjugacy class graph of G is defined as a graph with a vertex set represented by the non-central conjugacy classes of G. Two distinct vertices are connected if they have a common prime divisor. The main objective of this article is to find various topological indices including the Wiener index, the first Zagreb index and the second Zagreb index for the conjugacy class graph of dihedral groups of order 2n where the dihedral group is the group of symmetries of regular polygon, which includes rotations and reflections. Many topological indices have been determined for simple and connected graphs in general but not graphs related to groups. In this article, the Wiener index and Zagreb index of conjugacy class graph of dihedral groups are generalized. |
