动力学U(n)量子群

The dynamical U(n) quantum group

Erik Koelink, Yvette van Norden

摘要:

本文研究了矩阵代数M(n)的动力学模拟,M(n)是由Etingof和Varchenko给出的一个动力学R-矩阵构成的。这个代数的左和右corepresentation,这可以被看作是外部代数表示的类似物,被定义为这些corepresentation的矩阵元素,这定义动态量子小行列式。这些元素进行了更详细的研究,特别是行动的余乘和拉普拉斯展开式。利用拉普拉斯展开式,我们可以证明动力学量子行列式几乎是中心的,并且在相邻的一个逆中可以定义对极。这导致与动态R-矩阵相关联的动态GL(n)量子群。我们研究了导致动力学U(n)量子群的 *-结构,并得到了由R-矩阵产生的正则对的结果.

英文摘要:

We study the dynamical analogue of the matrix algebra M(n), constructed from a dynamical R-matrix given by Etingof and Varchenko. A left and a right corepresentation of this algebra, which can be seen as analogues of the exterior algebra representation, are defined and this defines dynamical quantum minor determinants as the matrix elements of these corepresentations. These elements are studied in more detail, especially the action of the comultiplication and Laplace expansions. Using the Laplace expansions we can prove that the dynamical quantum determinant is almost central, and adjoining an inverse the antipode can be defined. This results in the dynamical GL(n) quantum group associated to the dynamical R-matrix. We study a *-structure leading to the dynamical U(n) quantum group, and we obtain results for the canonical pairing arising from the R-matrix.
