WebIn this paper, we determine some sharp bounds on the symmetric division deg index of graphs and line graphs and characterize the corresponding extremal graphs. Keywords line graph, symmetric division deg index, bound. Mathematics Subject Classification: 05C07, 05C09, 05C92 1 Introduction We use U to denote the cardinality of set U. Web25 de fev. de 2024 · Recently, a novel topological invariant based on degrees of end-vertices of an edge in a graph was put forward. It was named Sombor index. The definition of the Sombor invariant suggests another, rather a geometric view onto graph edges. Here, the mathematical relations between the Sombor index and some other well-known … 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 patch cos\\u0027è
