Bouns for symmetric division degree index

In this thesis, the Symmetric division degree index, one of the chemical applications of graph theory, is examined. First, the basic definitions and theorems are presented. Second, the Vertex Symmetric division degree index is defined with the aim of obtaining sharp boundaries by providing a different perspective. Third, the Symmetric division degree indices and co-indices of the Symmetric division degree index of some special graphs are calculated. Finally, the Symmetric division degree indices of some important alkanes are found, and the breadth search algorithm is calculated. Thus, different theories emerge for the Symmetric division degree index.
