AI总结:

本文针对循环悬挂星、循环链、棱柱和广义书等新图族,给出了此前未知的素数顶点标号,即用1到n的整数单射标号顶点,使相邻顶点标号互素。

摘要:

一个简单且连通的$n$顶点图具有素数顶点标号,如果其顶点可以被单射地标号为整数$1, 2, 3,\ldots, n$,使得相邻顶点具有互素的标号。我们将为新的图族(包括循环悬挂星、循环链、棱柱和广义书)呈现此前未知的素数顶点标号。

英文摘要:

A simple and connected $n$-vertex graph has a prime vertex labeling if the vertices can be injectively labeled with the integers $1, 2, 3,\ldots, n$, such that adjacent vertices have relatively prime labels. We will present previously unknown prime vertex labelings for new families of graphs including cycle pendant stars, cycle chains, prisms, and generalized books.
