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…

Quantizations of generalized-Witt algebra and of Jacobson-Witt algebra in the modular case
Naihong Hu, Xiuling Wang
We quantize the generalized-Witt algebra in characteristic 0 with its Lie bialgebra structures discovered by Song-Su (\cite{GY}). Via a modulo p reduction and a modulo "p-restricte…
