Extremal problems on saturation for the family of -edge-connected graphs
Hui Lei, Suil O, Yongtang Shi +2
Let be a family of graphs. A graph is -saturated if contains no member of as a subgraph but contains some member of $\mathcal…
Star 5-edge-colorings of subcubic multigraphs
Hui Lei, Yongtang Shi, Zi-Xia Song +1
The star chromatic index of a multigraph , denoted , is the minimum number of colors needed to properly color the edges of such that no path or cycle of length fo…
Total rainbow connection of digraphs
Hui Lei, Henry Liu, Colton Magnant +1
An edge-coloured path is rainbow if its edges have distinct colours. For a connected graph , the rainbow connection number (resp. strong rainbow connection number) of is the…
Rainbow vertex connection of digraphs
Hui Lei, Shasha Li, Henry Liu +1
An edge-coloured path is \emph{rainbow} if its edges have distinct colours. An edge-coloured connected graph is said to be \emph{rainbow connected} if any two vertices are connecte…
