On a general class of elliptic equations in divergence form
We consider a general class of non-uniformly elliptic equations in divergence form. A priori estimate for \(W^{1,1}\) solutions of such equations, combined with an excess decay lemma, allow us to prove a partial regularity theorem and a Liouville type theorem.
