Korn-Maxwell-Sobolev inequalities for general incompatibilities
F Gmeineder, P Lewintan, P Neff - arXiv preprint arXiv:2212.13227, 2022 - arxiv.org
We establish a family of coercive Korn-type inequalities for generalised incompatible fields
in the superlinear growth regime under sharp criteria. This extends and unifies several …
