星积代数的协变强Morita理论

Covariant Strong Morita Theory of Star Product Algebras

Stefan Waldmann

摘要:

本文回顾了环C = R(i)上 *-代数的表示论的一些最新进展,其中R是有序的,i^2 =-1。表示空间是辅助 *-代数上的模,其内积取值于该辅助 *-代数。环排序允许实现对内积的正性要求。然后要求表示与内积相容。此外,我们可以以霍普夫代数作用的形式加入对称性的概念。对于所有这些概念的表示有一个完善的森田理论,我们审查。每个版本的森田理论的核心是相应的皮卡广群,我们给工具来计算和确定的轨道和各向同性组。

英文摘要:

In this note we recall some recent progress in understanding the representation theory of *-algebras over rings C = R(i) where R is ordered and i^2 = -1. The representation spaces are modules over auxiliary *-algebras with inner products taking values in this auxiliary *-algebra. The ring ordering allows to implement positivity requirements for the inner products. Then the representations are required to be compatible with the inner product. Moreover, one can add the notion of symmetry in form of Hopf algebra actions. For all these notions of representations there is a well-established Morita theory which we review. The core of each version of Morita theory is the corresponding Picard groupoid for which we give tools to compute and determine both the orbits and the isotropy groups.
