Convex PBW-Type Lyndon Bases and Restricted Two-parameter Quantum Groups of Type B
Naihong Hu, Xiuling Wang
We construct convex PBW-type Lyndon bases for two-parameter quantum groups U_{r,s}({so}_{2n+1}) with detailed commutation relations. It turns out that under a certain condition, th…

Convex PBW-type Lyndon Basis and Restricted Two-parameter Quantum Group of Type G_2
Naihong Hu, Xiuling Wang
We construct finite-dimensional pointed Hopf algebras \mathfrak u_{r,s}(G_2) (i.e. restricted 2-parameter quantum groups) from the 2-parameter quantum group U_{r,s}(G_2) defined in…
