Abstract:
We classify all the Hopf PBW-deformations of a new type quantum group Uq(sl2) from which the classical Drinfeld-Jimbo quantum group Uq(2) can arise as an almost unique nontrivial one. Different from the Uq(sl 2) case, the category of finite-dimensional Uq(sl 2)-modules is non-semisimple. We establish a block decomposition theorem for the category Uq(sl 2)-mod wt of finite-dimensional weight modules of Uq(sl 2). On the level of tensor category, we show that Uq(sl 2)-mod wt (respectively, the category Uq(sl 2)-mod of finite-dimensional Uq(sl 2)-modules) can be realized via (respectively, deformed) preprojective algebras of Dynkin type . © 2024 World Scientific Publishing Company.
