摘要

本文定义了一类新的受限量子群Ūq(sl2*)，确定了其Hopf poincar - birkhoff - witt -deformations Ūq(sl2*，κ)，其中Ūq(sl2*，0)=Ūq(sl2*)，并包含经典的受限Drinfeld-Jimbo量子群Ūq(sl2)。首先证明Ūq(sl2*)是一个基本的Hopf代数，然后通过与Ūq(sl2*)的Gabriel颤振相对应的(变形)预投影代数的商统一实现Ūq(sl2*)和Ūq(sl2)。此外，我们得到了Ūq(sl2*)和Ūq(sl2)的一致张量分类实现，这与上述hopf代数实现是一致的。

A new type restricted quantum group

In this paper, we define a new type restricted quantum group Ūq(sl2*) and determine its Hopf Poincaré-Birkhoff-Witt-deformations Ūq(sl2*,κ) in which Ūq(sl2*,0)=Ūq(sl2*) and the classical restricted Drinfeld–Jimbo quantum group Ūq(sl2) is included. We show that Ūq(sl2*) is a basic Hopf algebra, then uniformly realize Ūq(sl2*) and Ūq(sl2) via some quotients of (deformed) preprojective algebras corresponding to the Gabriel quiver of Ūq(sl2*). Moreover, we obtain a uniform tensor-categorical realization of Ūq(sl2*) and Ūq(sl2), which is consistent with the above-mentioned Hopf-algebraic realization.
