Classical r-matrices, “elliptic” BCS and Gaudin-type hamiltonians and spectral problem

In this article we make a brief review of the generalized Gaudin spin chains with [21] and without [18], [19] external magnetic field in the simplest case of g=so(3) and provide the r-matrix interpretation and generalization of the recent results of [38], [39], [40], on their exact solution. We pres...
