%0 Journal Article %T Paths with exponential intersection tails and oriented percolation %A Itai Benjamini %A Robin Pemantle %A Yuval Peres %J Mathematics %D 1997 %I arXiv %X We show that oriented percolation occurs whenever a condition is satisfied called "exponential intersection tails". This condition says that a measure on paths exists for which the probability of two independent paths intersecting in more than k sites is exponentially small in k. %U http://arxiv.org/abs/math/9701227v1
