A question on DFT

["Armando Navarro" <qoajnv - at - usc.es>]

 Dear members:
 I have a doubt about the Kohn-Sham implementation of DFT theory.
 Provide we would have the "true" functional, we can in principle =
 determine the "true" electronic density. But, it could be always =
 represented as a single determinant of Kohn-Sham molecular orbitals?
 Thanks in Advance
