Facial [r,s,t]-Colorings of Plane Graphs
Let G be a plane graph. Two edges are facially adjacent in G if they are consecutive edges on the boundary walk of a face of G. Given nonnegative integers r, s, and t, a facial [r, s, t]-coloring of a plane graph G = (V,E) is a mapping f : V ∪ E → {1, . . ., k} such that |f(v1) − f(v2)| ≥ r for ever...
