Description | We show that every plane graph with maximum face size four in which all faces of size four are vertex-disjoint is cyclically 5-colorable. This answers a question of Albertson whether graphs drawn in the plane with all crossings independent are 5-colorable. (C) 2009 Wiley Periodicals, Inc. J Graph Theory 64: 184-205. 2010 |
