摘要
In this paper, we study the local regularity of very weak solution u is an element of L-loc(1) (Omega) of the elliptic equation D-j(a(ij)(x)D(i)u) = f - D(i)g(i). Using the bootstrap argument and the difference quotient method, we obtain that if a(ij) is an element of C-loc(0,1) (Omega), g(i) is an element of L-loc(p) (Omega) and f is an element of L-loc(Op) (Omega) with 1 < p < infinity, then u is an element of W-loc(1,p) (Omega). Furthermore, we consider the higher regularity of u.
