We solve the Backlund problem for both the compact and noncompact versions of the Ishimori $(2+1)$-dimensional nonlinear spin model. In particular, we realize the arising Backlund algebra in the form of an infinite-dimensional loop Lie algebra of the Kac–Moody type.
Keywords: integrable systems, nonlinear spin models, Backlund transformations, Backlund–Cartan connections.
Mots-clés : prolongation algebras
