In this setting, we derive an explicit regularity exponent that depends only on universal parameters. Additionally, we prove non-degeneracy properties, providing further geometric insights into the nature of these solutions. Our regularity estimates not only improve but also extend, to some extent, the previously obtained results for zero-obstacle and dead-core problems driven by the $\\infty$-Laplacian. As an application of our findings, we also address some Liouville-type results for this class of equations.", "revisions": [ { "version": "v1", "updated": "2024-10-25T21:07:05.000Z" } ], "analyses": { "subjects": [ "35B65", "35J60", "35J94" ], "keywords": [ "regularity estimates", "hardy-hénon-type equations driven", "dead-core problems driven", "explicit regularity exponent", "viscosity solutions" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
