网格的立方体魔术标号

Cube-magic labelings of grids

Rachel Wulan Nirmalasari Wijaya, Joe Ryan, Thomas Kalinowski

摘要:

证明了$d$维格图$G=(V,E)$($d\geqslant 2$)的顶点和边可以分别用$\{1,\ldots,\lvert V\rvert\}$和$\{1,\ldots,\lvert E\rvert\}$中的整数进行标号,使得对于每个同构于$d$ -立方体的子图$H$,$H$的所有标号之和相同.因此,对于每个$d\geqslant 2$,每个$d$维网格图是$Q_d$ -supermagic,其中$Q_d$是$d$ -立方体。

英文摘要:

We show that the vertices and edges of a $d$-dimensional grid graph $G=(V,E)$ ($d\geqslant 2$) can be labeled with the integers from $\{1,\ldots,\lvert V\rvert\}$ and $\{1,\ldots,\lvert E\rvert\}$, respectively, in such a way that for every subgraph $H$ isomorphic to a $d$-cube the sum of all the labels of $H$ is the same. As a consequence, for every $d\geqslant 2$, every $d$-dimensional grid graph is $Q_d$-supermagic where $Q_d$ is the $d$-cube.
