## Abstract The relationship between well known necessary conditions for __N__‐representability of the reduced two‐density matrix is investigated. It is shown that the __G__‐condition implies two conditions of the operator endomorphism type: the __C__‐ and the __B__‐condition.

## Abstract __N__‐representability conditions for a two‐particle density operator implied by positive‐semidefiniteness of the projection operator __P__^__N__+1^(ϕ^1^ Λ Ψ^__N__^) are derived and discussed. The operator __P__^__N__+1^(ϕ^1^ Λ Ψ^__N__^) projects onto an (__N__ + 1)‐particle antisymmetr
