关于L-Grundy序列的长度

On the length of L-Grundy sequences

Rebekah Herrman, Stephen G. Z. Smith

摘要:

图的L-序列$G $是不同顶点的序列$S = \{v_1, ... , v_k\}$使得$N[v_i] \setminus \cup_{j=1}^{i-1} N(v_j) \neq \emptyset$ .最长的L-序列的长度称为L-Grundy控制数,记作$γ_{gr}^L(G)$。在本文中,我们证明了$γ_{gr}^L(G) \leq n(G) - δ(G) + 1$,这是由Brear,Gologranc,Henning和Kos证明的。我们还证明了一些早期的结果$n$ -顶点图的特点,如$γ_{gr}^L(G) = n$,以及在图操作下的L-Grundy数的变化的界限。

英文摘要:

An L- sequence of a graph $G $ is a sequence of distinct vertices $S = \{v_1, ... , v_k\}$ such that $N[v_i] \setminus \cup_{j=1}^{i-1} N(v_j) \neq \emptyset$. The length of the longest L-sequence is called the L-Grundy domination number, denoted $γ_{gr}^L(G)$. In this paper, we prove $γ_{gr}^L(G) \leq n(G) - δ(G) + 1$, which was conjectured by Bre{š}ar, Gologranc, Henning, and Kos. We also prove some early results about characteristics of $n$-vertex graphs such $γ_{gr}^L(G) = n$, as well as bounds on the change in L-Grundy number under graph operations.
