The associated Laplace-Beltrami operator is of the form of a Grushin operator plus a singular potential. In a supercritical parameter regime, we identify the rate of concentration and profile of the high-frequency eigenfunctions that accumulate at the boundary. We give an application to acoustic modes on gas planets.", "revisions": [ { "version": "v1", "updated": "2024-10-27T19:32:28.000Z" } ], "analyses": { "subjects": [ "58C40", "53C17", "35P20" ], "keywords": [ "singular riemannian manifolds", "concentration", "compact riemannian manifold", "grushin operator plus", "singular potential" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
