This operator is a generalization of the so called bi-harmonic Laplacian $\\Delta^2$. Here, we also established basic functional properties of $\\Delta_g^2$, which can be applied to existence results. Afterwards, we study the eigenvalues of $\\Delta_g^2$, which depend on normalisation conditions, due to the lack of homogeneity of the operator. Finally, we study different nonlinear eigenvalue problems associated to $\\Delta_g^2$ and we show regimes where the corresponding spectrum concentrate at $0$, $\\infty$ or coincide with $(0, \\infty)$.", "revisions": [ { "version": "v1", "updated": "2024-11-02T15:04:07.000Z" } ], "analyses": { "subjects": [ "46E30", "35P30", "35D30" ], "keywords": [ "nonlinear eigenvalue problems", "orlicz-sobolev spaces", "biharmonic operator", "higher-order laplacian operator", "established basic functional properties" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
