We prove an existence and uniqueness theorem for the elliptic Dirichlet problem for the equation div a(x,∇u) = f in a planar domain Ω. Here fL1(Ω) and the solution belongs to the so-called grand Sobolev space W01,2)(Ω). This is the proper space when the right hand side is assumed to be only L1-integrable. In particular, we obtain the exponential integrability of the solution, which in the linear case was previously proved by Brezis-Merle and Chanillo-Li.
