q-对易关系的Fock空间表示的精确性

Exactness of the Fock space representation of the q-commutation relations

Matthew Kennedy, Alexandru Nica

摘要:

证明了对区间(-1,1)中的任意q,q-对易关系的Fock表示可以酉嵌入到扩展Cuntz代数的Fock表示中.特别地,这意味着由q-对易关系的Fock表示生成的C* 代数是精确的。一个直接的结果是q-高斯冯诺依曼代数对区间(-1,1)中的所有q都是弱正合的。

英文摘要:

We show that for all q in the interval (-1,1), the Fock representation of the q-commutation relations can be unitarily embedded into the Fock representation of the extended Cuntz algebra. In particular, this implies that the C*-algebra generated by the Fock representation of the q-commutation relations is exact. An immediate consequence is that the q-Gaussian von Neumann algebra is weakly exact for all q in the interval (-1,1).
