This model describes a single particle on a random potential in statistical physics. We derive asymptotic formulas for the mean number of critical points of index $k$ with critical values in an open set as the dimension $N$ goes to infinity. In a companion paper, we provide the same analysis without the index constraint.", "revisions": [ { "version": "v1", "updated": "2022-06-28T09:06:32.000Z" } ], "analyses": { "keywords": [ "gaussian random fields", "isotropic increments", "critical points", "smooth gaussian process", "landscape complexity" ], "note": { "typesetting": "TeX", "pages": 50, "language": "en", "license": "arXiv", "status": "editable" } } }
