WebIn this paper, we investigate some properties of this graph invariant in terms of orbit structure of a graph and then we explore new bounds forsdd-index. In continuing, the inverse symmetric division deg index is defined and new results concerning these two graph indices are stablished. Finally, some bounds for both indices are presented. 展开 Web25 de out. de 2024 · This index (SDD(G)) which is vertex degree-based topological index is defined as ∑((〖d_u〗^2+〖d_v〗^2)⁄(d_u d_v)).
