Examples of admissible operators include those expressing pointwise, unilateral, integral isoperimetric, elliptic quasilinear differential, jacobian and null Lagrangian constraints. Via the method of $L^p$ approximations as $p\\to \\infty$, we illustrate the existence of a special $L^\\infty$ minimiser which solves a divergence PDE system involving certain auxiliary measures as coefficients. This system can be seen as a divergence form counterpart of the Aronsson PDE system which is associated with the constrained $L^\\infty$ variational problem.", "revisions": [ { "version": "v1", "updated": "2022-02-24T10:30:42.000Z" } ], "analyses": { "subjects": [ "35J94", "49J20", "49K20", "49K35", "49K99", "35J92" ], "keywords": [ "isosupremic vectorial minimisation problems", "general nonlinear constraints", "general quasiconvex first order functionals", "pde system" ], "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable" } } }
