Title: Yangians, Quantum Loop Algebras And Elliptic Quantum Groups
Abstract This talk will focus on three affine quantum groups associated to a simple Lie algebra, namely the Yangian, quantum loop algebra and elliptic quantum group. These correspond respectively to rational, trigonometric and elliptic solutions of the Yang–Baxter equation, and arise in their simplest guises as symmetries of Heisen- berg XXX, XXZ and XYZ lattice models. In a joint work with V. Toledano Laredo, we showed how to construct representations of the quantum loop algebra from those of the Yangian, and vice versa, thus settling the long standing problem of relating their representations. I will explain this construction and its extension to the case of elliptic quantum groups.
