Maria Elena Griseta, Janusz Wysoczański

AI总结:

该研究定义了由有限个湮灭算子生成的弱单调C*-代数,证明其同构于特定Cuntz-Krieger C*-代数的商代数,同时指出其对角子代数为MASA并给出Gelfand谱的详细刻画。

摘要:

我们研究作用于弱单调Fock空间上、由有限多个湮灭算子生成的C*-代数,将其称为弱单调C*-代数。我们给出该代数的一种抽象表示,证明它同构于对应某一合适矩阵A的Cuntz-Krieger C*-代数$\u27e8\uc4f6\ud835\udc4a\u27e9$的一个适当商代数。此外,我们证明弱单调C*-代数的对角子代数是一个MASA(极大阿贝尔子代数),并详细描述了其Gelfand谱。

英文摘要:

We consider the $C^*$-algebra generated by finitely many annihilation operators acting on the weakly monotone Fock space, and we call it weakly monotone $C^*$-algebra. We give an abstract representation for this algebra, showing that it is isomorphic to a suitable quotient of a Cuntz-Krieger $C^*$-algebra $\mathcal{O}_A$ corresponding to a suitable matrix $A$. Furthermore, we show that the diagonal subalgebra of the weakly monotone $C^*$-algebra is a MASA and we give the detailed description of its Gelfand spectrum.
