$C^*$ -代数中几乎正规变元的多项式

Polynomials of almost-normal arguments in $C^*$-algebras

Nikolay Filonov, Ilya Kachkovskiy

摘要:

$C^*$ -代数正规元的谓词演算是一种重要的分析工具。我们认为多项式$p(a,a^*)$的元素$a$与小的自换向器规范$\|[a,a^*]\| \le δ$,并表明,许多性能的谓词演算保留模错误的顺序$δ$。

英文摘要:

The functional calculus for normal elements in $C^*$-algebras is an important tool of analysis. We consider polynomials $p(a,a^*)$ for elements $a$ with small self-commutator norm $\|[a,a^*]\| \le δ$ and show that many properties of the functional calculus are retained modulo an error of order $δ$.
