Abstract

We study a generalized Stokes system with Orlicz growth which is nonstandard in a non-smooth domain. Our purpose is to derive a Calderon-Zygmund type estimate of the gradient of a solution and the pressure to such a system like (1.1) under a small BMO non-linearity and a sufficient flatness on the boundary of the domain. In the process, we overcome not only lack of Lipschitz regularity for the corresponding limiting problem, but also the fact that the associated structure depends only on the symmetric part of the gradient for the desired global estimate, which is new even in the literature of elliptic system on a nonsmooth domain.
