Abstract
Certain lower bounds to the ground state energy of N-fermion systems have been derived in the literature using the properties of reduced density matrices.It is indicated that while some good approximations to the energy may be obtained by similar consideration the rigorous lower bound expressions lie too far below the exact energy to prove generally useful.
