(mathematics)
The problem of determining the critical threshold concentration of conducting links in a pecolation network at which an infinite cluster of conducting links is formed and the lattice transforms from an insulator to a conductor.

A continuum percolation problem had received attention in the 1970s in a network of sintered glass and metallic particles.
There are, however, differences between a typical bond percolation problem and the present system.
Even in the simplest case, that of the two-dimensional square lattice site percolation, does not exist nowadays an exact solution of the percolation problem, and no exact results are known on any kind of lattice in three dimensions [7].
In a typical percolation problem, one has randomly distributed sites connected by percolation channels.
