C*-伪乘酉与Hopf C*-双模

C*-pseudo-multiplicative unitaries and Hopf C*-bimodules

Thomas Timmermann

摘要:

在C* 代数的背景下,引入C*-伪乘法幺正和具体的Hopf C*-双模来研究量子广群.这些幺正和Hopf C*-双模推广了乘法幺正和Hopf C* 代数,并且是Enock,Lebrant和Vallin研究的伪乘法幺正和Hopf-von Neumann双模的类似物.对于每一个C*-伪乘法酉模,我们将两个傅立叶代数与一个对偶对、一个C*-张量范畴的表示联系起来,在正则情况下,我们将两个约化的和两个泛Hopf C*-双模联系起来。该理论说明了与局部紧豪斯多夫群胚的例子。特别地,我们得到了局部紧Hausdorff广群的连续Fourier代数。

英文摘要:

We introduce C*-pseudo-multiplicative unitaries and concrete Hopf C*-bimodules for the study of quantum groupoids in the setting of C*-algebras. These unitaries and Hopf C*-bimodules generalize multiplicative unitaries and Hopf C*-algebras and are analogues of the pseudo-multiplicative unitaries and Hopf--von Neumann-bimod-ules studied by Enock, Lesieur and Vallin. To each C*-pseudo-multiplicative unitary, we associate two Fourier algebras with a duality pairing, a C*-tensor category of representations, and in the regular case two reduced and two universal Hopf C*-bimodules. The theory is illustrated by examples related to locally compact Hausdorff groupoids. In particular, we obtain a continuous Fourier algebra for a locally compact Hausdorff groupoid.
