When the exponent is large, the existence and multiplicity of solutions strongly depend on the geometric properties of the domain, which also deeply affect their qualitative behavior. Remarkably, a wide variety of solutions, both positive and sign-changing, have been found when the exponent is sufficiently large. In this paper, we focus on this topic and fine new sign-changing solutions that exhibit an unexpected concentration phenomenon as the exponent approaches infinity.", "revisions": [ { "version": "v1", "updated": "2024-07-22T15:42:45.000Z" } ], "analyses": { "subjects": [ "35J25", "35B40", "35B44" ], "keywords": [ "lane-emden problem", "planar domains", "exponent approaches infinity", "geometric properties", "unexpected concentration phenomenon" ], "note": { "typesetting": "TeX", "pages": 41, "language": "en", "license": "arXiv", "status": "editable" } } }
