设G是一个有限群
S是G的一个子集(可以含G的单位元).Bi-Cayley图BC(G
S)是一个二部图:其顶点集为G×{0
1}
而边集为{{(g
0)
(sg
1)}:g∈G
s∈S}.本文证明了有限交换群上连通的Bi-Cayley图BC(G
S)是Hamilton的
如果S-1=S且S含二阶元或单位元.
Let $G$ be a finite group
$S$(possibly
contains the identity element) be a subset of$G$. The Bi-Cayley graph $BC(G
S)$ is a bipartite graph with vertex set $G×{0
1}$ and edge set ${{(g
1)}
g∈G
s∈S$. In this paper
we show that every connected Bi-Cayley graph $BC(G
S)$ on a finite abelian group is hamiltonian if $S+{-1}=S$ and $S$ contains the identity element or an element of order 2.
