its uniqueness part, you can also check it by trying all possible. The simplest nontrivial example is that of the 2-dimensional elliptic equation (x) = (1 - x)(1 - x)(1 -. They proved the uniqueness theorem by deriving the positivity of the corresponding Laplace operator in a spectral representation.
