Abstract:

Given a plane graph G = (V,E,F), we can define the vertex coloring for V, the edge coloring for E, the face coloring for F, the total coloring for V ∪ E, the coupled coloring for V ∪F, the edge-face coloring for E ∪F, and the entire coloring V ∪ E ∪ F, such that adjacent or incident elements have different colors. In this talk we shall give a survey on these colorings and list colorings of plane graphs. Some recent results and open problems about this direction are mentioned.
