经典空间的量子对称性

Quantum symmetries of classical spaces

Jyotishman Bhowmick, Debashish Goswami, Subrata Shyam Roy

摘要:

给出了在经典拓扑空间上构造真(非交换的$C^*$代数)紧量子群的忠实作用的一般方案.使用这个,我们表明:(i)紧致连通的经典空间可以通过真正的紧致量子群具有忠实作用,以及(ii)在经典连通的紧空间上存在谱三元组,对于该谱三元组,方向和体积保持等距的量子群(在\cite{qorient}的意义上)是真正的量子群.

英文摘要:

We give a general scheme for constructing faithful actions of genuine (noncommutative as $C^*$ algebra) compact quantum groups on classical topological spaces. Using this, we show that: (i) a compact connected classical space can have a faithful action by a genuine compact quantum group, and (ii) there exists a spectral triple on a classical connected compact space for which the quantum group of orientation and volume preserving isometries (in the sense of \cite{qorient}) is a genuine quantum group.
