Specifically, we define a zero-sum game on a percolation configuration of $\\mathbb{Z}^2$, where two players move a token along the non-oriented edges of $\\mathbb{Z}^2$, collecting a cost of 1 for each edge that is open, and 0 otherwise. The total cost is given by the limit superior of the average cost. We demonstrate that the value of this game is deterministic and equals 1 if and only if the percolation parameter exceeds $p_c$, the critical exponent of oriented percolation. Additionally, we establish that the value of the game is continuous at $p_c$. Finally, we show that for $p$ close to 0, the value of the game is equal to 0.", "revisions": [ { "version": "v1", "updated": "2024-08-25T10:00:27.000Z" } ], "analyses": { "subjects": [ "60K35", "91A15" ], "keywords": [ "oriented percolation", "zero-sum game", "percolation parameter exceeds", "percolation configuration", "average cost" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
