Optimal partial regularity for quasilinear elliptic systems with VMO coefficients based on A-harmonic approximations
Haiyan Yu, Shenzhou Zheng · DOAJ (DOAJ: Directory of Open Access Journals) · 2015
In this article, we consider quasi-linear elliptic systems in divergence form with discontinuous coefficients under controllable growth. We establish an optimal partial regularity of the weak solutions by a modification of A-harmonic approximation argument introduced by Duzaar and Grotowski.
