We study fine properties of the gradient of the solution to the conductivity equation div (σ(x) u(x)) = 0 in bounded domains. Our analysis is restricted to dimension two and it is concerned with merely measurable, elliptic coefficients. We establish sharp results on the higher order of integrability of the modulus of the gradient and of the inverse of the modulus of the gradient of the solution...
