摘要：

We consider spin models of the form S,t = γS,x+S ∧ (αS,xx+βS,x). They can be interpreted as one-dimesional reductions of the three-dimensional classical, continuous, inhomogeneous Heisenberg ferromagnet. We isolate integrable subcases corresponding to non-isospectral (in x and t) deformations of the standard, quadratic in the spectral parameter, su (2) AKNS linear problem. © 1990.
