Abstract
. Communication networks can be represented as graphs, where vertices represent network nodes and edges represent connections between them. Various graph theory parameters, such as connectivity, toughness, tenacity, binding number, scattering number, and integrity, were presented to assess the vulnerability of networks. Calculating the values of these vulnerability parameters can be challenging, particularly for certain classes of graphs, such as Generalized Petersen Graphs ( G P G ), due to their diverse structures. This paper establishes upper and lower bounds for the tenacity of G P G . We demonstrate a lower bound of 1 for the tenacity ( ( ) ) , ( k n G P G T ), across all values of n and k. Additionally, we explore the tenacity values of G P G and present a general upper bound for the tenacity value in this graph type. By using the relationship between the tenacity parameter and the connectivity ( ) G κ and toughness ( ) G t parameters, we also update some theorems related to the connectivity and toughness of GPG .
.通信网络可以表示为图,其中顶点代表网络节点,边代表节点之间的连接。为评估网络的脆弱性,提出了各种图论参数,如连通性、韧性、顽强性、结合数、散布数和完整性。由于广义彼得森图(G P G)的结构多种多样,计算这些脆弱性参数的值可能具有挑战性,特别是对于某些类别的图。本文确定了 G P G 韧性的上限和下限。我们证明了韧性的下界为 1 ( ( ) )此外,我们还探讨了 G P G 的韧性值,并提出了该图类型韧性值的一般上限。通过利用韧性参数与连通性 ( ) G κ 和韧性 ( ) G t 参数之间的关系,我们还更新了一些与 GPG 的连通性和韧性相关的定理。
