Harnack's inequality for quasilinear elliptic equations with coefficients in Morrey spaces
Local boundedness and Harnack's inequality for equations of the form \(\text{div} A(x,u,u_ x) + B(x,u,u_ x)\) are proved. It is considered the situation when the coefficients in the growth conditions are elements of Morrey spaces instead of \(L_ p\)-spaces. The author follows ideas of J. Serrin and uses an inequality of C. Fefferman.
