Inspired by recent works of Brezis-Nguyen and Baer-Jerison on the Jacobian and Hessian determinants, we show that the distributional $m$th-Jacobian minors of degree $r$ are weak continuous in fractional Sobolev spaces $W^{m-\\frac{m}{r},r}$, and the result is optimal, satisfying the necessary conditions, in the frame work of fractional Sobolev spaces. In particular, the conditions can be removed in case $m=1,2$, i.e., the $m$th-Jacobian minors of degree $r$ are well defined in $W^{s,p}$ if and only if $W^{s,p} \\subseteq W^{m-\\frac{m}{r},m}$ in case $m=1,2$.", "revisions": [ { "version": "v1", "updated": "2018-08-22T02:29:53.000Z" } ], "analyses": { "subjects": [ "46E35", "46F10", "42B35" ], "keywords": [ "fractional sobolev spaces", "distributional hyper-jacobian determinants", "th-jacobian minors", "necessary conditions", "baer-jerison" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable" } } }
