奇数度的正则图是反幻图

Regular graphs of odd degree are antimagic

Daniel W. Cranston

摘要:

一个具有$m$边的图$G$的反幻标号是从$E(G)$到$\{1,2,\ldots,m\}$的双射,使得对于所有的顶点$u$和$v$,与$u$关联的边的标号之和不同于与$v$关联的边的标号之和. Hartsfield和Ringel证明了除单边图$K_2$之外的所有连通图都有反魔标号.我们对奇数度的正则图证明了这个猜想。

英文摘要:

An antimagic labeling of a graph $G$ with $m$ edges is a bijection from $E(G)$ to $\{1,2,\ldots,m\}$ such that for all vertices $u$ and $v$, the sum of labels on edges incident to $u$ differs from that for edges incident to $v$. Hartsfield and Ringel conjectured that every connected graph other than the single edge $K_2$ has an antimagic labeling. We prove this conjecture for regular graphs of odd degree.
