谱三元组的无限直和的例子

Examples of infinite direct sums of spectral triples

Kevin Falk

摘要:

本文研究了非交换谱三元组无限族的两种求和方法。首先,我们给出了谱三重积分的定义,并给出了一个例子,利用Toeplitz算子代数作用在$\mathbb{C}^n$的单位球上的加权Bergman空间。其次,利用Hardy空间上的Toeplitz算子代数构造了$\mathbb{C}$中一般多边形自相似集的谱三元组.在这种情况下,我们表明,我们可以恢复的Hausdorff维数的分形集。

英文摘要:

We study two ways of summing an infinite family of noncommutative spectral triples. First, we propose a definition of the integration of spectral triples and give an example using algebras of Toeplitz operators acting on weighted Bergman spaces over the unit ball of $\mathbb{C}^n$. Secondly, we construct a spectral triple associated to a general polygonal self-similar set in $\mathbb{C}$ using algebras of Toeplitz operators on Hardy spaces. In this case, we show that we can recover the Hausdorff dimension of the fractal set.
