Assuming certain conditions on $a,\\, p,\\, q$ and $r$, we derive a succinct Cheng-Yau type gradient estimate for such solutions. This gradient estimate allows us to obtain a Liouville-type theorem and a Harnack inequality. Our Liouville-type result is novel even in Euclidean space", "revisions": [ { "version": "v1", "updated": "2023-11-05T05:22:58.000Z" } ], "analyses": { "subjects": [ "58J05", "35B45", "35J92" ], "keywords": [ "complete riemannian manifold", "nash-moser iteration approach", "quasilinear elliptic equations", "liouville property", "succinct cheng-yau type gradient estimate" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
