Solutions for two conjectures on kaleidoscopic edge-colorings

Xueliang Li, Xiaoyu Zhu

For an $r$ -regular graph $G$ , we define an edge-coloring $c$ with colors from ${1, 2, \dots,$ $k}$ , in such a way that any vertex of $G$ is incident to at least one edge of each c…

Distance proper connection of graphs and their complements

Xueliang Li, Colton Magnant, Meiqin Wei +1

Let $G$ be an edge-colored connected graph. A path $P$ in $G$ is called a distance $ℓ$ -proper path if no two edges of the same color can appear with less than $ℓ$ edges in be…
