Non-symmetrizable Quantum Groups: Defining Ideals and SpecializationXin Fang (1) Universität Köln, Germany
Two generating sets of the dening 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
