We give two "complementary" descriptions of the curve $\Gamma$ parametrizing double-Bloch solutions to the difference analogue of the Lam\'e equation. The curve depends on a positive integer number $\ell$ and two continuous parameters: the "lattice spacing" $\eta$ and the modular parameter $\tau$. Apart from being a covering of the elliptic curve with the modular parameter $\tau$, $\Gamma$ is a hyperelliptic curve of genus $2\ell$. We also point out connections between the spectral curve and… 



Vacuum curves of elliptic L-operators and representations of Sklyanin algebra

An algebro-geometric approach to representations of Sklyanin algebra is proposed. To each 2 \times 2 quantum L-operator an algebraic curve parametrizing its possible vacuum states is associated. This

Algebraic integrability of the two-body Ruijsenaars operator

We study the algebra of difference operators that commute with the two-body Ruijsenaars operator, a $q$-deformation of the Lam\'e differential operator, for generic values of the deformation

Spin generalization of the Ruijsenaars-Schneider model, non-abelian 2D Toda chain and representations of Sklyanin algebra

Action-angle type variables for spin generalizations of the elliptic Ruijsenaars-Schneider system are constructed. The equations of motion of these systems are solved in terms of Riemann

An algebro-geometric construction of commuting operators and of solutions to the Toda lattice equation , Korteweg deVries equation and related non-linear equations

A remarkable "dictionary" was discovered by I.M. Krichever [7], following suggestions in the work of Zaharov-Shabat [11], where they attempted to find a common formalism for the inverse scattering

Generalized Bethe ansatz with the general spin representations of the Sklyanin algebra

The quantum inverse scattering method is applied to the inhomogeneous Heisenberg XYZ model with general spins, i.e. the general spin representations of the Sklyanin algebra. By means of the

Yang-Baxter equation and representation theory: I

The problem of constructing the GL(N,ℂ) solutions to the Yang-Baxter equation (factorizedS-matrices) is considered. In caseN=2 all the solutions for arbitrarily finite-dimensional irreducible
