R-matrices for Elliptic Calogero-Moser Models
نویسندگان
چکیده
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 inclusion of a spectral parameter enables us to find R-matrices for the general elliptic potential.

R-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 کاملDynamical r-matrices for the Elliptic Calogero-Moser Model
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...
متن کاملA pr 1 99 6 Elliptic Ruijsenaars – Schneider and Calogero – Moser hierarchies are governed by the same r – matrix
We demonstrate that in a certain gauge the elliptic Ruijsenaars– Schneider models admit Lax representation governed by the same dynamical r– matrix as their non–relativistic counterparts (Calogero–Moser models). This phenomenon was previously observed for the rational and hyperbolic models.
