As main model we have the function $\\Phi(t)=(e^{t^{2}}-1)/2$. Here, we study some situations where it is possible to work with global minimization, local minimization and mountain pass theorem, however some estimates are not standard for this type of problem.", "revisions": [ { "version": "v1", "updated": "2017-04-11T22:52:02.000Z" } ], "analyses": { "keywords": [ "orlicz-sobolev space", "quasilinear problem", "mountain pass theorem", "smooth bounded domain", "main model" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
