Exchange Dynamical Quantum Groups

  • P. Etingof

For any simple Lie algebra ? and any complex number q which is not zero or a nontrivial root of unity, %but may be equal to 1 we construct a dynamical quantum group (Hopf algebroid), whose representation theory is essentially the same as the representation theory of the quantum group U q (?). This dynamical quantum group is obtained from the fusion and exchange relations between intertwining operators in representation theory of U q (?), and is an algebraic structure standing behind these relations.
