Uniqueness of solutions to the Laplace and Poisson equations
... 6. Why is the Poisson equation with Cauchy boundary conditions ill-posed? In the case of Cauchy boundary conditions (where both u and ∂u/∂n are simultaneously specified on S), the same arguments employed above can again be used to prove that if a solution exists it must be unique. Unfortunately, in ...
