Under the wider ranges of exponents of $g$ and $f$, the well-posedness of the weak solution is achieved by establishing a priori space-time estimates. Then, the existence of the global attractor in the naturally phase space $H^1_0(\\Omega)\\times L^2(\\Omega)$ is obtained. Moreover, we prove that the global attrator is regular, that is, the global attractor is a bounded subset of $(H^2(\\Omega)\\cap H^1_0(\\Omega))\\times H^1_0(\\Omega)$.", "revisions": [ { "version": "v1", "updated": "2023-08-11T16:14:20.000Z" } ], "analyses": { "keywords": [ "global attractor", "nonlinear damping", "super-cubic nonlinearity", "well-posedness", "semilinear wave equation" ], "note": { "typesetting": "TeX", "pages": 33, "language": "en", "license": "arXiv", "status": "editable" } } }
