题目：Hamiltonian circles of the prism of infinite cubic graphs

主讲人：李斌龙

摘要：A circle of a infinite locally finite graph $G$ is a homeomorphic mapping of the unit circle $S^1$ in $|G|$, the Freudenthal compactification of $G$. A circle of $G$ is

Hamiltonian if it meets every vertex (and then every end) of $G$. Paulraja proved that for every 3-connected cubic finite graph $G$, the prism of $G$ (the Cartesian product of $G$ and $K_2$) is Hamiltonian. We extended the result to infinite graphs, showing that if $G$ is an infinite locally finite graph, then its prism has a Hamiltonian circle.
