单位球Bergman空间上Toeplitz代数的一类理想

On a Class of Ideals of the Toeplitz Algebra on the Bergman Space of the Unit Ball

Trieu Le

摘要:

令$\mathfrak{T}$表示单位球$\mathbb{B}_n.$的Bergman空间上的全Toeplitz代数对于$L^{\infty},$的每个子集$G$令$\mathfrak{CI}(G)$表示由所有$T_fT_g-T_gT_f$与$f,g\in G.$生成的$\mathfrak{T}$的闭双边理想已知$\mathfrak{CI}(C(\bar{\mathbb{B}}_n))=\mathcal{K}$ -紧算子的理想和$\mathfrak{CI}(C(\mathbb{B}_n))=\mathfrak{T}.$尽管有这些"极值情况“,$\mathfrak{T}$确实包含其他非平凡理想。本文给出了$L^{\infty}$的一类子集$G$的构造,使得$\mathcal{K}\subsetneq\mathfrak{CI}(G)\subsetneq\mathfrak{T}.$

英文摘要:

Let $\mathfrak{T}$ denote the full Toeplitz algebra on the Bergman space of the unit ball $\mathbb{B}_n.$ For each subset $G$ of $L^{\infty},$ let $\mathfrak{CI}(G)$ denote the closed two-sided ideal of $\mathfrak{T}$ generated by all $T_fT_g-T_gT_f$ with $f,g\in G.$ It is known that $\mathfrak{CI}(C(\bar{\mathbb{B}}_n))=\mathcal{K}$ - the ideal of compact operators and $\mathfrak{CI}(C(\mathbb{B}_n))=\mathfrak{T}.$ Despite these ``extremal cases'', $\mathfrak{T}$ does contain other non-trivial ideals. This paper gives a construction of a class of subsets $G$ of $L^{\infty}$ so that $\mathcal{K}\subsetneq\mathfrak{CI}(G)\subsetneq\mathfrak{T}.$
