In statistical physics and mathematics, percolation theory describes the behavior of a network when nodes or links are added. This is a geometric type of phase transition, since at a critical fraction of addition the network of small, disconnected clusters merge into significantly larger connected, so-called … See more A representative question (and the source of the name) is as follows. Assume that some liquid is poured on top of some porous material. Will the liquid be able to make its way from hole to hole and reach the bottom? This … See more For most infinite lattice graphs, pc cannot be calculated exactly, though in some cases pc there is an exact value. For example: • for … See more Subcritical and supercritical The main fact in the subcritical phase is "exponential decay".
