Permutation symmetry implications

The interpretation of Eq. (1.2) in terms of permutational symmetry of determinants is clear. To make the analogous content of Eqs. (1.4) and (1.5) more transparent, we now examine some of the implications that follow from these equations. Let us first examine Eq. (1.5). For r = s, this reads rr+ — 1. When operating on a ket in which is occupied, the first...
