We obtain existence and multiplicity for $\\varepsilon>0$ small, where the number of solutions is related to the cup-length of a set of local minima of $V$. Furthermore, these solutions are proved to concentrate in the potential well, exhibiting a polynomial decay. We highlight that these results are new also in the limiting local setting $s=1$ and $N\\geq 3$, with an exponential decay of the solutions.", "revisions": [ { "version": "v1", "updated": "2021-01-02T12:53:53.000Z" } ], "analyses": { "subjects": [ "35A15", "35B25", "35B33", "35Q55", "35R11", "47J30", "58E05" ], "keywords": [ "fractional nls equations", "concentration results", "critical growth", "multiplicity", "satisfying general berestycki-lions type conditions" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
