Abstract. In this short note we clarify some issues regarding the existence of mini-
mizers for the Thomas-Fermi-von Weiszacker energy functional in orbital-free density
functional theory, when the Wang-Teter corrections are included.
1 Introduction
In [1] it was claimed that there always exists a minimizer; however, the statement of
Theorem 2.1 is incomplete. In this note we present the full statement, with a detailed
proof.
The theorem stated in [1] holds as long as the number of electrons is below a certain
critical value. The correct statement for the theorem in [1] is:
Theorem 1.1 (Existence of minimizers). Given v C(), and KWT L2
