%0 Journal Article %T Free boson representation of DY_{\hbar}(gl_N)_k %A X. M. Ding %A B. Y. Hou %A B. Yuan Hou %A L. Zhao %J Mathematics %D 1997 %I arXiv %R 10.1063/1.532288 %X We construct a realization of the Yangian double DY_\hbar(gl_N) and DY_\hbar(sl_N) of an arbitrary level k in terms of free boson fields with a continuous parameter. In the \hbar \to 0 limit this realization becomes the Wakimoto realization of kac-Moody algebra gl_N and sl_N, respectively. The vertex operators and the screening currents are also constructed with the same spirits; the screening currents commute with DY_\hbar(sl_N) modulo total difference. %U http://arxiv.org/abs/hep-th/9709016v1
