Аннотация:
We prove the commutativity of the first two nontrivial integrals of motion for
quantum spin chains with elliptic form of the exchange interaction. We also show their liner
independence for the number of spins larger than 4. As a byproduct, we obtained several
identities between elliptic Weierstrass functions of three and four arguments.
Ключевые слова:
quantum elliptic spin chains, transpositions, integrability.
