      Perturbations of elliptic operators in chord arc domains 

      Milakis, Emmanouil; Pipher, Jill; Toro, Tatiana (AMS, 2014)
      We study the boundary regularity of solutions to divergence form operators which are small perturbations of operators for which the boundary regularity of solutions is known. An operator is a small perturbation of another ...
