色数

If for any uv∈E, C_u≠C_v, then we callσis a k-adjacent vertex distinguishing incidence coloring of G andχ_=min{k| there exists a k- adjacent vertex distinguishing incidence coloring of G} is the adjacent vertex distinguishing incidence chromatic number of G.

若对任意uv∈E满足C_u≠C_v，则称σ为G的k-邻点可区别关联着色，并称X_=min{k|存在G的k-邻点可区别关联着色}为G的邻点可区别关联色数。
