%0 Journal Article %T Quantum groupoids associated to universal dynamical R-matrices %A Ping Xu %J Mathematics %D 1998 %I arXiv %R 10.1016/S0764-4442(99)80219-5 %X By using twist construction, we obtain a quantum groupoid $\cald\ot_{q}\uqg$ for any simple Lie algebra $\frakg$. The underlying Hopf algebroid structure encodes all the information of the corresponding elliptic quantum group-the quasi-Hopf algebras as obtained by Fronsdal, Arnaudon et. al. and Jimbo et. al.. %U http://arxiv.org/abs/math/9811172v1
