Transfer-matrix commutativity conjecture. The transfer matrices are mutually commuting and commute with all these local conserved quantities:

Transfer-matrix commutativity conjecture. Transfer matrices with different spectral parameters mutually commute:

Let $N=2M$ with $M\geq 2$, and let $mu_1,mu_2,mu_k$ be Bethe roots in the BAE for the periodic XYZ chain. Let $ell_1$ denote the elliptic function appearing in those equations, and…

Let $N=2M$ be the even length of the periodic XYZ chain, and let the chiral basis be the basis constructed in the paper. The Bethe ansatz equations (BAE) determine eigenstates, whi…
