Some probabilistic restatements of the Four Color Conjecture
Yuri Matiyasevich · Journal of Graph Theory · 2004
Abstract With every triangulation of sphere, we associate a probabilistic space in a natural way and define several random events. The Four Color Conjecture (4CC) turns out to be equivalent to different statements about positive correlation among some pairs of these events. © 2004 Wiley Periodicals, Inc.
