Bäcklund Transformation for the BC-Type Toda Lattice

نویسنده

  • EVGENY K. SKLYANIN
چکیده

We study an integrable case of n-particle Toda lattice: open chain with boundary terms containing 4 parameters. For this model we construct a Bäcklund transformation and prove its basic properties: canonicity, commutativity and spectrality. The Bäcklund transformation can be also viewed as a discretized time dynamics. Two Lax matrices are used: of order 2 and of order 2n + 2, which are mutually dual, sharing the same spectral curve.

Multi-component generalizations of four integrable differential-difference equations: soliton solutions and bilinear Bäcklund transformations

Bilinear approach is applied to derive integrable multi-component generalizations of the socalled 1+1 dimensional special Toda lattice, the Volterra lattice, a simple differential-difference equation found by Adler, Moser, Weiss, Veselov and Shabat and another integrable lattice reduced from the discrete BKP equation. Their soliton solutions expressed by pfaffians and the corresponding bilinear...

On the Structure of the Bäcklund Transformations for the Relativistic Lattices

The Bäcklund transformations for the relativistic lattices of the Toda type and their discrete analogues can be obtained as the composition of two duality transformations. The condition of invariance under this composition allows to distinguish effectively the integrable cases. Iterations of the Bäcklund transformations can be described in the terms of nonrelativistic lattices of the Toda type....

Few remarks on Bäcklund transformations for many-body systems

Using the n-particle periodic Toda lattice and the relativistic generalization due to Ruijsenaars of the elliptic Calogero-Moser system as examples, we revise the basic properties of the Bäcklund transformations (BT’s) from the Hamiltonian point of view. The analogy between BT and Baxter’s quantum Q-operator pointed out by Pasquier and Gaudin is exploited to produce a conjugated variable μ for ...
