List-recoloring of two classes of planar graphs

Chenran Pan, Weifan Wang, Runrun Liu

For a graph $G$ with a list assignment $L$ and two $L$-colorings $\hat{I}\pm$ and ${\hat{I}}^2$, an $L$-recoloring sequence from $\hat{I}\pm$ to ${\hat{I}}^2$ is a sequence of proper $L$-colorings where consecutive…
