A Mathematical Aspect of Hohenberg-Kohn Theorem. (arXiv:1709.07118v1 [physics.chem-ph])
The Hohenberg-Kohn theorem plays a fundamental role in density functional
theory, which has become a basic tool for the study of electronic structure of
matter. In this article, we study the Hohenberg-Kohn theorem for a class of
external potentials based on a unique continuation principle.
