对称函数空间到算子理想的同构嵌入的缺乏
Lack of isomorphic embeddings of symmetric function spaces into operator ideals
摘要:
设$E(0,1)$是$(0,1)$上的对称空间,$C_F$是与对称序列空间$F$相关联的Hilbert空间$\ell_2$上紧算子的对称理想.我们给出了$E(0,1)$和$ F$的几个准则,使$E(0,1)$不嵌入理想的$C_F$,扩展了Arazy和Lindenstrauss的结果,当$E(0,1)=L_p(0,1)$和$F=\ell_p $,$1\le p<\infty$,由于情况。
英文摘要:
Let $E(0,1)$ be a symmetric space on $(0,1)$ and $C_F$ be a symmetric ideal of compact operators on the Hilbert space $\ell_2$ associated with a symmetric sequence space $F$. We give several criteria for $E(0,1)$ and $ F$ so that $E(0,1)$ does not embed into the ideal $C_F$, extending the result for the case when $E(0,1)=L_p(0,1)$ and $F=\ell_p $, $1\le p<\infty$, due to Arazy and Lindenstrauss.
