$\Uq$的量子Casimir算符及其本征值
The quantum Casimir operators of $\Uq$ and their eigenvalues
摘要:
我们证明了Bracken,Gould和Zhang的早期工作中构造的量子线性群的量子Casimir算符加上一个额外的中心元生成$\Uq$的整个中心.作为证明的副产品,我们得到了这些量子Casimir算子的本征值的有趣的新公式,这些公式用经典一般线性代数的一类有限维不可约表示的特征标表示。
英文摘要:
We show that the quantum Casimir operators of the quantum linear group constructed in early work of Bracken, Gould and Zhang together with one extra central element generate the entire center of $\Uq$. As a by product of the proof, we obtain intriguing new formulae for eigenvalues of these quantum Casimir operators, which are expressed in terms of the characters of a class of finite dimensional irreducible representations of the classical general linear algebra.
