In this paper, we assume that $c$ and $h$ are allowed to change sign such that $c^{+}\\not \\equiv 0$, then we prove the existence of at least two bounded solutions when $\\|c\\|_{k}$ and $\\|h\\|_{k}$ are suitably small. For this purpose, we use the Mountain Pass theorem, due to Ambrosetti and Rabinowitz, on a problem with variational structure reduced from $(P)$. Here, the main difficulty is that the nonlinearity term considered does not satisfy Ambrosetti and Rabinowitz condition. The key idea is to replace the Ambrosetti and Rabinowitz condition by the \\textbf{nonquadraticity condition at infinity}.", "revisions": [ { "version": "v1", "updated": "2017-10-10T08:13:53.000Z" } ], "analyses": { "keywords": [ "elliptic problem", "laplacian type", "gradient term", "multiplicity", "rabinowitz condition" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
