Abstract
We consider a class of equations in divergence form with a singular/degenerate weight (equation presented) Under suitable regularity assumptions for the matrix A, the forcing term f and the field F, we prove Hölder continuity of solutions which are odd in y 2 R, and possibly of their derivatives. In addition, we show stability of the C0;α and C1;α a priori bounds for approximating problems in the form (equation presented) as ϵ → 0. Our method is based upon blow-up and appropriate Liouville type theorems.
