R. Quiroga-Barranco, N. Vasilevski

摘要:

设$D$是$\mathbb{C}^n$中以原点为中心的有界拓扑凸完备Reinhardt整环.推广了一维单位圆盘情形的一个结果,证明了由具有有界可测分别径向符号的Toeplitz算子生成的$C^*$ -代数(即,仅依赖于$|z_1|$、$|z_2|$、.的符号,$|z_n|$)是可交换的。我们表明,自然行动的$n$维环面$\mathbb{T}^n$定义(在一定的开放充分措施子集的$D$)的叶理进行横向黎曼结构具有杰出的几何特征。它的叶与Bergman度量等距,且这些叶的切丛的正交补可积于全测地叶理。进一步证明了这两个叶理是拉格朗日的。然后,我们指定的单位球所获得的结果。

英文摘要:

Let $D$ be a bounded logarithmically convex complete Reinhardt domain in $\mathbb{C}^n$ centered at the origin. Generalizing a result for the one-dimensional case of the unit disk, we prove that the $C^*$-algebra generated by Toeplitz operators with bounded measurable separately radial symbols (i.e., symbols depending only on $|z_1|$, $|z_2|$, ..., $|z_n|$) is commutative. We show that the natural action of the $n$-dimensional torus $\mathbb{T}^n$ defines (on a certain open full measure subset of $D$) a foliation which carries a transverse Riemannian structure having distinguished geometric features. Its leaves are equidistant with respect to the Bergman metric, and the orthogonal complement to the tangent bundle of such leaves is integrable to a totally geodesic foliation. Furthermore, these two foliations are proved to be Lagrangian. We specify then the obtained results for the unit ball.
