Perturbation of the domain and regularity of the solutions of the bipolar fluid flow equations in polygonal domains
The paper treats the stability of the solutions to the bipolar flow equations with respect to perturbations of the boundary by Lipschitz curves. Also the regularity of the solution to the bipolar flow equations in a polygonal domain is studied. The local singularities of the solution around a corner is calculated, and then it is shown that there are no other singularities.
