Topological indices are widely used for characterizing molecular graphs, establishing relationships between structure and properties of molecules. In this article we discuss adjacency matrix and three topological indices: Wiener index, Laplacian energy and Zagreb indices of zero-divisor graphs of \(\mathbb {Z}_n\). We also provide a MATLAB code for Laplacian energy and Zagreb indices of \(\varGamma (\mathbb {Z}_n)\).

零除数图$$ \ varGamma（Z_n）$$Γ（Z n）的邻接矩阵和维纳指数

拓扑索引已广泛用于表征分子图，建立分子的结构与性质之间的关系。在本文中，我们讨论\（\ mathbb {Z} _n \）的零除数图的邻接矩阵和三个拓扑指数：Wiener指数，Laplacian能量和Zagreb指数。我们还提供了MATLAB代码，用于\（\ varGamma（\ mathbb {Z} _n）\）的拉普拉斯能量和Zagreb索引。
