树及其它图类的邻素标号

Neighborhood-Prime Labelings of Trees and Other Classes of Graphs

Malori Cloys, N. Bradley Fox

摘要:

图的邻域素标号是素标号的一种变体,其中顶点被分配从$1$到$|V(G)|$的标号,使得每个非度$1$顶点的邻域中的标号的$\gcd$等于$1$。在本文中,我们研究了几类图,如多边形蛇和书籍,重点是树木,包括毛毛虫,蜘蛛和鞭炮的邻域素标号。

英文摘要:

A neighborhood-prime labeling of a graph is a variation of a prime labeling in which the vertices are assigned labels from $1$ to $|V(G)|$ such that the $\gcd$ of the labels in the neighborhood of each non-degree $1$ vertex is equal to $1$. In this paper, we examine neighborhood-prime labelings of several classes of graphs such as polygonal snakes and books, with a focus on trees including caterpillars, spiders, and firecrackers.
