The Darboux-Bäcklund transformation for the static 2-dimensional continuum Heisenberg chain
نویسندگان
چکیده
We construct the Darboux-Bäcklund transformation for the sigma model describing static configurations of the 2-dimensional classical continuum Heisenberg chain. The transformation is characterized by a non-trivial normalization matrix depending on the background solution. In order to obtain the transformation we use a new, more general, spectral problem.

Discrete canonical system and non-Abelian Toda lattice: Bäcklund-Darboux transformation and Weyl functions
A version of the iterated Bäcklund-Darboux transformation, where Darboux matrix takes a form of the tranfer matrix function from the system theory, is introduced for the discrete canonical system and nonAbelian Toda lattice. Solutions are constructed and several spectral results are obtained.
متن کاملBäcklund–Darboux Transformation for Non-Isospectral Canonical System and Riemann–Hilbert Problem
A GBDT version of the Bäcklund–Darboux transformation is constructed for a non-isospectral canonical system, which plays essential role in the theory of random matrix models. The corresponding Riemann–Hilbert problem is treated and some explicit formulas are obtained. A related inverse problem is formulated and solved.
متن کاملBäcklund–Darboux Transformations and Discretizations of Super KdV Equation
For a generalized super KdV equation, three Darboux transformations and the corresponding Bäcklund transformations are constructed. The compatibility of these Darboux transformations leads to three discrete systems and their Lax representations. The reduction of one of the Bäcklund–Darboux transformations and the corresponding discrete system are considered for Kupershmidt’s super KdV equation....
متن کاملBinary Darboux-Bäcklund Transformations for the Manin-Radul Super KdV Hierarchy
We construct the supersymmetric extensions of the Darboux-Bäcklund transformations (DBTs) for the Manin-Radul super KdV hierarchy using the super-pseudo-differential operators. The elementary DBTs are triggered by the gauge operators constructed from the wave functions and adjoint wave functions of the hierarchy. Iterating these elementary DBTs, we obtain not only Wronskian type but also binary...
متن کاملA new approach to the Darboux-Bäcklund transformation versus the standard dressing method
We present a new approach to the construction of the Darboux matrix. This is a generalization of the recently formulated method based on the assumption that the square of the Darboux matrix vanishes for some values of the spectral parameter. We consider the multisoliton case, the reduction problem and the discrete case. The relationship between our approach and the standard dressing method is d...
