Non-symmetrizable Quantum Groups: Defining Ideals and Specialization

Xin Fang[1]

(1) Universität Köln, Germany

Two generating sets of the de ning ideal of a Nichols algebra of diagonal type were proposed, which are then applied to study the bar involution and the specialization problem for quantum groups associated to non-symmetrizable generalized Cartan matrices.

Keywords: Nichols algebra, quantum group, defining ideal, specialization
