| Abstract: | We construct a realization of the quantum affine algebra  of an arbitrary level k in terms of free boson fields. In the q 1 limit this realization becomes the Wakimoto realization of . The screening currents and the vertex operators (primary fields) are also constructed; the former commutes with modulo total difference, and the latter creates the highest weight state from the vacuum state of the boson Fock space.fellow of Soryushi ShogakukaiAddress after June 1: Department of Physics, Faculty of Liberal Arts, Shinshu University, Matsumoto 390, Japan |
