摘要

2010年，Gutman引入了一个新的图不变量Sombor索引SO，定义为$sqrt{deg(u)^{2}+deg(v)^{2}}。本文给出了Sombor指数与一些基于度的拓扑指数:Zagreb指数、Forgotten指数和Randi' {c}指数之间的关系。在无三角形图类中建立了相似关系。

Relations between Sombor Index and some Degree-Based Topological Indices

In [13] Gutman introduced a novel graph invariant called Sombor index SO, defined via $sqrt{deg(u)^{2}+deg(v)^{2}}.$ In this paper we provide relations between Sombor index and some degree-based topological indices: Zagreb indices, Forgotten index and Randi' {c} index. Similar relations are established in the class of triangle-free graphs.
