图的随机提升中的Hamilton圈

Hamilton Cycles in Random Lifts of Graphs

Tomasz Łuczak, Łukasz Witkowski, Marcin Witkowski

摘要:

对于图$G$,$G$的随机$n$提升是通过用一组$n$顶点代替图的每个顶点,并在$G$的相应顶点相邻时通过随机匹配连接一对集合来获得的.证明了图$G$的随机提升是Hamilton的,只要$G$的最小度至少为$5$,且包含两个不相交的哈密顿圈,且其并不是二部图.

英文摘要:

For a graph $G$ the random $n$-lift of $G$ is obtained by replacing each of its vertices by a set of $n$ vertices, and joining a pair of sets by a random matching whenever the corresponding vertices of $G$ are adjacent. We show that asymptotically almost surely the random lift of a graph $G$ is hamiltonian, provided $G$ has the minimum degree at least $5$ and contains two disjoint Hamiltonian cycles whose union is not a bipartite graph.
