摘要
We consider weak solutions u is an element of u(0) + W-0(1,2) (Omega, R-N) boolean AND L-infinity (Omega, R-N) of second-order nonlinear elliptic systems of the type -div a (. , u, Du) = (. , u, Du) in Omega with an inhomogeneity satisfying a natural growth condition. In dimensions n is an element of {2, 3, 4}, we show that Hn-1-almost every boundary point is a regular point for Du, provided that the boundary data and the coefficients are sufficiently smooth.
