摘要

增强萨格勒布指数（AZI）是一种重要的基于顶点度的拓扑指数，在化学领域有很多应用。本文获得了 AZI(G)的最小值，并描述了具有七个或七个以上顶点的连通四环图类中相应极值图的特征。这些结果可用于表征具有四环结构的化合物的许多化学特性。

Extremal properties of connected 4-cyclic graphs of a topological index related to chemical graphs.

Augmented Zagreb index (AZI) is an important vertex-degree-based topological index with many applications especially in chemistry. In this article, minimum value of $A Z I (G)$ is obtained and the corresponding extremal graph is characterized in the class of connected 4-cyclic graphs with seven or more vertices. These results can be used to characterize numerous chemical properties of chemical compounds having 4-cyclic structures.
