The Ginzburg-Landau objective functional combines a double well potential, that favours indicator valued function, and the $p$-Laplacian, that enforces regularity. Under appropriate scaling between the two terms minimisers exhibit a phase transition on the order of $\\epsilon=\\epsilon_n$ where $n$ is the number of data points. We study the large data asymptotics, i.e. as $n\\to \\infty$, in the regime where $\\epsilon_n\\to 0$. The mathematical tool used to address this question is $\\Gamma$-convergence. In particular, it is proved that the discrete model converges to a weighted anisotropic perimeter.", "revisions": [ { "version": "v1", "updated": "2018-02-23T19:21:33.000Z" } ], "analyses": { "keywords": [ "phase transition model", "large data limit", "point clouds", "nonlocal anisotropic ginzburg-landau type functional", "p-laplacian" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
