Double-bosonization and Majid's conjecture, (I): rank-induction of $ABCD$

Abstract

Majid developed in \cite{majid3} his double-bosonization theory to construct $U_q(\mathfrak{g})$ and expected to generate inductively not just a line but a tree of quantum groups starting from a node. In this paper, the authors confirm the Majid's first expectation (see p. 178 \cite{majid3}) through giving and verifying the full details of the inductive constructions of $U_q(\mathfrak{g})$ for the classical types, i.e., the $ABCD$ series. Some examples in low ranks are given to elucidate that any quantum group of classical type can be constructed from the node corresponding to $U_q({\mathfrak{sl}}_2)$.
