小图与路圈的笛卡儿积的安全控制数

The Secure Domination Number of Cartesian Products of Small Graphs with Paths and Cycles

Michael Haythorpe, Alex Newcombe

摘要:

确定了两个小图与路或圈的笛卡儿积的安全控制数,以及Mobius梯图的安全控制数。在此之前的工作,在所有的情况下,安全控制数已被确定,证明要么是平凡的,或已来自下界建立考虑不同形式的控制。然而,后一种模式的证明是不适用于大多数图,包括那些考虑在这里。因此,这项工作代表了第一次尝试,以确定安全控制数通过安全控制本身的性质,预计这些方法可能会被用来确定在未来的进一步结果。

英文摘要:

The secure domination numbers of the Cartesian products of two small graphs with paths or cycles is determined, as well as for Mobius ladder graphs. Prior to this work, in all cases where the secure domination number has been determined, the proof has either been trivial, or has been derived from lower bounds established by considering different forms of domination. However, the latter mode of proof is not applicable for most graphs, including those considered here. Hence, this work represents the first attempt to determine secure domination numbers via the properties of secure domination itself, and it is expected that these methods may be used to determine further results in the future.
