Dynamical r-matrices for the Elliptic Calogero-Moser Model
نویسنده
چکیده
For the integrable N -particle Calogero-Moser system with elliptic potential it is shown that the Lax operator found by Krichever possesses a classical r-matrix structure. The r-matrix is a natural generalisation of the matrix found recently by Avan and Talon (hep-th/9210128) for the trigonometric potential. The r-matrix depends on the spectral parameter and only half of the dynamical variables (particles’ coordinates). It satisfies a generalized Yang-Baxter equation involving another dynamical matrix.

R-matrices for Elliptic Calogero-Moser Models
The classical R-matrix structure for the n-particle Calogero-Moser models with (type IV) elliptic potentials is investigated. We show there is no momentum independent R-matrix (without spectral parameter) when n ≥ 4. The assumption of momentum independence is sufficient to reproduce the dynamical R-matrices of Avan and Talon for the type I,II,III degenerations of the elliptic potential. The inc...
متن کاملR-Matrices, Generalized Inverses and Calogero-Moser-Sutherland Models
Four results are given that address the existence, ambiguities and construction of a classical R-matrix given a Lax pair. They enable the uniform construction of R-matrices in terms of any generalized inverse of ad(L). For generic L a generalized inverse (and indeed the Moore-Penrose inverse) is explicitly constructed. The R-matrices are in general momentum dependent and dynamical. We apply our...
متن کامل7 A Conjectured R - Matrix
A new spectral parameter independent R-matrix (that depends on all of the dynamical variables) is proposed for the elliptic Calogero-Moser models. Necessary and sufficient conditions for this R-matrix to exist reduce to an equality between determinants of matrices involving elliptic functions. The needed identity appears new and is still unproven in full generality: we present it as a conjecture.
متن کاملThe non-dynamical r-matrices of the degenerate Calogero-Moser models
A complete description of the non-dynamical r-matrices of the degenerate Calogero-Moser models based on gln is presented. First the most general momentum independent r-matrices are given for the standard Lax representation of these systems and those r-matrices whose coordinate dependence can be gauged away are selected. Then the constant r-matrices resulting from gauge transformation are determ...
متن کاملThe nondynamical r-matrix structure for the elliptic An−1 Calogero-Moser model
In this paper, we construct a new Lax operator for the elliptic An−1 Calogero-Moser model with general n(2 ≤ n) from the classical dynamical twisting, in which the corresponding r-matrix is purely numeric (nondynamical one). The nondynamical r-matrix structure of this Lax operator is obtained, which is elliptic Zn-symmetric r-matrix. Mathematics Subject Classification : 70F10 , 70H33 , 81U10.
