Non-trivial percolation transition conjecture for supercritical random planar maps
Fix and consider site percolation on with open boundary condition: boundary vertices are open, while each interior vertex is independently open with probability and closed with probability . An open cluster is a connected component of the open vertices. Critical percolation probability conjecture. There exists such that, for every and every , almost surely there are no infinite open clusters, whereas for and every , the open cluster containing is infinite with positive probability. This asserts a non-trivial phase transition, while the behavior at is addressed separately.
