講座內(nèi)容:
A proper edge-coloring of a graph G is strict neighbor-distinguishing if for any two adjacent vertices u and v, the set of colors used on the edges incident with u and the set of colors used on the edges incident with v are not included in each other. The strict neighbor distinguishing index χ_snd^' (G) of G is the minimum number of colors in a strict neighbor-distinguishing edge-coloring of G. In this talk, we investigate the strict neighbor-distinguishing edge coloring of general graphs, planar graphs, K_4-minor-free graphs, and outerplanar graphs. We also discuss the related coloring problems of graphs, including neighbor-distinguishing edge coloring and local neighbor-distinguishing edge coloring. Some open problems will be provided.
