# Crossing probabilities for planar percolation.

@article{KohlerSchindler2020CrossingPF, title={Crossing probabilities for planar percolation.}, author={Laurin Kohler-Schindler and V. Tassion}, journal={arXiv: Probability}, year={2020} }

We prove a general Russo-Seymour-Welsh result valid for any invariant planar percolation process satisfying positive association. This means that the probability of crossing a rectangle in the long direction is related by a homeomorphism to the probability of crossing it in the short direction. This homeomorphism is universal in the sense that it depends only on the aspect ratio of the rectangle, and is uniform in the scale and the considered model.
