Regularity results for the gradient of solutions of a class of linear elliptic systems with data

We prove that if a vector-function f belongs to the Morrey space , with , n≥3, N≥2, λ]0,n−2], and u is the solution of the system

then Du belongs to the space , for any , provided the matrix of bounded measurable coefficients (A_ij) has sufficiently small dispersion of the eigenvalues.
