In the focusing case, we characterize the dichotomy\r\nbetween this behaviour and blowup for initial data with energy less than that\r\nof the ground state.\r\nThese results rely on analogous statements for the two-dimensional cubic\r\nnonlinear Schr¨odinger equation, which are known in the defocusing case and\r\nfor spherically-symmetric initial data in the focusing case. Thus, our results\r\nare mostly unconditional.\r\nIt was previously shown by Nakanishi that spacetime bounds for Klein–\r\nGordon equations imply the same for nonlinear Schr¨odinger equations.","lang":"eng"}],"oa_version":"Published Version","publication_identifier":{"eissn":["1088-6850"],"issn":["0002-9947"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Mathematical Society","article_type":"original","date_created":"2026-06-19T07:31:10Z","OA_place":"publisher","day":"01","intvolume":" 364","das_tickbox":"1","oa":1,"article_processing_charge":"No","type":"journal_article","citation":{"ieee":"R.
