Starting with the usual square grid, keep all vertices untouched while erasing edges according as follows: for every integer $i$, the entire column of vertical edges contained in the line $\\{ x = i \\}$ is removed independently of other columns with probability $\\rho > 0$. Similarly, for every integer $j$, the entire row of horizontal edges contained in the line $\\{ y = j\\}$ is removed independently with probability $\\rho$. On the remaining random lattice, we perform Bernoulli bond percolation. Our main contribution is an alternative proof that the model undergoes a nontrivial phase transition, a result established earlier by Hoffman. The main novelty lies on the fact that the dynamic renormalization employed earlier is replaced by a static version, which is simpler and more robust to extend to different models. We emphasize the flexibility of our methods by showing the non-triviality of the phase transition for a new oriented percolation model in a random environment as well as for a model previously investigated by Kesten, Sidoravicius and Vares. We also prove a result about the sensitivity of the phase transition with respect to the stretching mechanism.", "revisions": [ { "version": "v1", "updated": "2023-11-24T18:20:29.000Z" } ], "analyses": { "subjects": [ "60K35", "82B43", "05C10" ], "keywords": [ "percolation phase transition", "stretched lattices", "perform bernoulli bond percolation", "nontrivial phase transition", "dynamic renormalization employed earlier" ], "note": { "typesetting": "TeX", "pages": 38, "language": "en", "license": "arXiv", "status": "editable" } } }
