Backlund transformations for the sl(2) Gaudin magnet

Exactly Solvable and Integrable Systems 2009-10-31 v2

Abstract

Elementary, one- and two-point, Backlund transformations are constructed for the generic case of the sl(2) Gaudin magnet. The spectrality property is used to construct these explicitly given, Poisson integrable maps which are time-discretizations of the continuous flows with any Hamiltonian from the spectral curve of the 2x2 Lax matrix.
