Uniqueness of discrete solutions of nonmonotone PDEs without a globally fine mesh condition

S Pollock, Y Zhu - Numerische Mathematik, 2018 - Springer
Uniqueness of the finite element solution for nonmonotone quasilinear problems of elliptic
type is established in one and two dimensions. In each case, we prove a comparison
theorem based on locally bounding the variation of the discrete solution over each element.
The uniqueness follows from this result, and does not require a globally small meshsize.
