Abstract

Abstract Sierpiński graphs are family of fractal nature graphs having applications in mathematics of Tower of Hanoi, topology, computer science, and many more diverse areas of science and technology. This family of graphs can be generated by taking certain number of copies of the same basic graph. A topological index is the number which shows some basic properties of the chemical structures. This article deals with degree based topological indices of uniform subdivision of the generalized Sierpiński graphs S(n,G) and Sierpiński gasket Sn. The closed formulae for the computation of different kinds of Zagreb indices, multiple Zagreb indices, reduced Zagreb indices, augmented Zagreb indices, Narumi-Katayama index, forgotten index, and Zagreb polynomials have been presented for the family of graphs.

Sierpiński图一致细分的一些拓扑性质

Sierpiński图是分形性质图的家族，在河内塔的数学、拓扑学、计算机科学和许多不同的科学和技术领域都有应用。这类图可以通过对相同的基本图进行一定数量的复制来生成。拓扑指数是表示化学结构的一些基本性质的数字。本文研究了广义Sierpiński图S(n,G)和Sierpiński垫片Sn的一致细分的基于度的拓扑指标。对图族给出了计算不同类型的萨格勒布指数、多重萨格勒布指数、约化萨格勒布指数、增广萨格勒布指数、Narumi-Katayama指数、遗忘指数和萨格勒布多项式的封闭公式。
