Searching for new conditions for fermion N-representability
Hubert Grudzinski, Jacek Hirsch
New elements of the dual cone of the set of fermion N-representable 2-density operators are proposed. So far, the explicit form of the corresponding necessary conditions for N-repr…

The N-representability problem, the pseudo-spectral decomposition of antisymmetric 1-body operators, and collective behaviour
Hubert Grudzinski
The pseudo--spectral decomposition of an --particle antisymmetric 1--body positive--semidefinite operator that corresponds to the canonical convex decomposition into the extreme…
