Integrable deformations of principal chiral model from solutions of associative Yang-Baxter equation

D. Domanevsky, A. Levin, M. Olshanetsky +1

We describe deformations of the classical principle chiral model and 1+1 Gaudin model related to ${\mathrm{GL}}_N$ Lie group. The deformations are generated by $R$-matrices satisfying t…
