单位球上具有对称、交错与反称分别径向符号的Toeplitz算子

Toeplitz operators with symmetric, alternating and anti-symmetric separately radial symbols on the unit ball

Armando Sánchez-Nungaray, José Rosales-Ortega, Carlos González-Flores

AI总结:

该研究利用纯表示论方法,证明单位球加权Bergman空间上由对称、交错分别径向符号对应的Toeplitz算子生成的$C^*$-代数均交换,且对称分别径向Toeplitz算子比径向Toeplitz算子更具一般性。

摘要:

我们研究了对称分别径向(对应群为$S_n\rtimes \mathbb{T}^n$)、交错分别径向(对应群为$A_n\rtimes \mathbb{T}^n$)符号,以及$\mathbb{C}^n$中单位球上加权Bergman空间上的相关Toeplitz算子。采用纯表示论方法,我们证明了由每一类此类Toeplitz算子生成的$C^*$-代数都是交换的。此外,我们表明对称分别径向Toeplitz算子比径向Toeplitz算子更具一般性,即每个径向Toeplitz算子都是对称分别径向的。

英文摘要:

We consider symmetric separately radial (with corresponding group $S_n\rtimes \mathbb{T}^n$) and alternating separately radial (with corresponding group $A_n\rtimes \mathbb{T}^n$) symbols, as well as the associated Toeplitz operators on the weighted Bergman spaces on the unit ball on $\mathbb{C}^n$. Using a purely representation theoretic approach we obtain that the $C^*$-algebras generated by each family of such Toeplitz operators is commutative. Furthermore, we show that the symmetric separately radial Toeplitz operators are more general than radial Toeplitz operators, i.e., every radial Toeplitz operator is a symmetric separately radial.
