摘要

摘要随机结构在化合物的组成中起着重要的作用，而拓扑指数是间接衡量化合物性质的重要指标。萨格勒布指数及其修订版(或重新定义版)是常用的化学拓扑指数，为测定化合物的各种物理化学性质提供了理论依据。本文利用概率论的技巧，确定了两类重要随机图G(n, p)和G(n, m)的约二阶萨格勒布指数和超萨格勒布指数。

Two modified Zagreb indices for random structures

Abstract Random structure plays an important role in the composition of compounds, and topological index is an important index to measure indirectly the properties of compounds. The Zagreb indices and its revised versions (or redefined versions) are frequently used chemical topological indices, which provide the theoretical basis for the determination of various physical-chemical properties of compounds. This article uses the tricks of probability theory to determine the reduced second Zagreb index and hyper-Zagreb index of two kinds of vital random graphs: G(n, p) and G(n, m).

期刊介绍： This journal is committed to the publication of short communications, original research, and review articles within the field of main group metal and semi-metal chemistry, Main Group Metal Chemistry is an open-access, peer-reviewed journal that publishes in ongoing way. Papers addressing the theoretical, spectroscopic, mechanistic and synthetic aspects of inorganic, coordination and organometallic main group metal and semi-metal compounds, including zinc, cadmium and mercury are welcome. The journal also publishes studies relating to environmental aspects of these metals, their toxicology, release pathways and fate. Articles on the applications of main group metal chemistry, including in the fields of polymer chemistry, agriculture, electronics and catalysis, are also accepted.
