However, in general we cannot absorb the sums over i′ and j′ separately to define reduced density matrices for A1 and A2, as in (16)

Rokhsar-Kivelson states with local constraints Taking a generic underlying statistical model (still satisfying local constraints), we have Ω ij B = Ω i′j′ B for i ∼ i′, j ∼ j′
