Incidence coloring of Regular graphs and Complement graphs
Pak Kiu Sun
Using a relation between domination number and incidence chromatic number, we obtain necessary and sufficient conditions for -regular graphs to be -incidence colorable. A…

Some Results on incidence coloring, star arboricity and domination number
Pak Kiu Sun, Wai Chee Shiu
Two inequalities bridging the three isolated graph invariants, incidence chromatic number, star arboricity and domination number, were established. Consequently, we deduced an uppe…
