Abstract
We study the regularity of solutions to degenerate AA-harmonic equations under suitable integrability assumptions on the ellipticity and growth coefficients. In particular we show a self-improving property of the gradient of the solutions, extending previous results by Gehring and Iwaniec–Sbordone valid in the uniformly elliptic setting.
