Title: Generalized quantum Gaudin spin chains, involutive automorphisms and 'twisted' classical r-matrices

Abstract

Using automorphisms {sigma} of finite-dimensional Lie algebras and classical skew-symmetric r-matrices we construct 'twisted' nonskew symmetric r-matrices with the spectral parameters. Using them and results of our previous papers we construct new quantum spin chains that generalize famous Gaudin spin chains. We consider several examples of the twisted nonskew symmetric r-matrices and the corresponding Gaudin-type systems.
