We consider the generalized AKNS systems, introduced and discussed recently in [1]. We have shown that the dressing techniques both in matrix pseudo-differential operators and formal series with respect to the spectral parameter can be developed for these hierarchies.On leave of absence from the ITP, Kiev 252143, Ukraine.

Some relations between different objects associated with quantum affine algebras are reviewed. It is shown that the Frenkel-Jing bosonization of a new realization of the quantum affine algebra
as well as bosonization of L-operators for this algebra can be obtained from Zamolodchikov-Faddeev algebras defined by the quantum R-matrix satisfying unitarity and crossing-symmetry conditions.On leave of absence from the ITP, Kiev 252143, Ukraine.

We study quantum integrable models with the GL(3) trigonometric R-matrix solvable by the nested algebraic Bethe ansatz and obtain an explicit representation for a scalar product of generic Bethe vectors in terms of a sum over partitions of Bethe parameters. This representation generalizes the known formula for scalar products in models with the GL(3)-invariant R-matrix. 相似文献

Two new hierarchies, MILW2 and a two-dimensional nonlocal Toda lattice are constructed. The characteristic property of the first one is the connection with the ILW2 hierarchy by means ofgl(2) Miura transformation. On the other hand, MILW2 equations turn out to be symmetry equations for a two-dimensional nonlocal Toda lattice. A new version of the dressing technique with quantized spectral parameter is proposed. 相似文献

Recent results, concerning the quantum relativistic Toda chain at root of unity, are interpreted in this note from the point
of view of invariant auxiliary linear problem. Such form of the linear problem arises in the three-dimensional integrable
systems, and several results from the three dimensional models are applied to the relativistic Toda chain.

The projections of the product of the Drinfeld’s currents onto intersections of the different Borel subalgebras in the current
realization of the quantum affine algebra
are calculated. It was shown that this projections has the structure of the off-shell nested Bethe ansatz vectors.
