摘要
We study the relationship among the XXZ Heisenberg model and three models obtained from it by various transformations. In particular, we emphasize the role of a non-trivial central element t(Z) in the underlying algebra and its relationship with the twisted boundary conditions, S-N+1(+/-) = t(+/-N)S(1)(+/-).
