Percolation of poisson sticks on the plane

Abstract

We consider a percolation model on the plane which consists of 1-dimensional sticks placed at points of a Poisson process on R2 each stick having a random, but bounded length and a random direction. The critical probabilities are defined with respect to the occupied clusters and vacant clusters and they are shown to be equal. The equality is shown through a 'pivotal cell' argument, using a version of the Russo-Seymour-Welsh theorem which we obtain for this model. © 1991 Springer-Verlag.
