Krivine定理的不可能推广
On impossible extensions of Krivine's Theorem
摘要:
我们给出两个巴拿赫空间的例子。一个巴拿赫空间没有包含$\ell_p$($1\le p<\infty$)或$c_0$的扩散模型。另一个空间有一个无条件基,其中$\ell_p$($1\le p<\infty$)和$c_0$是在所有块基中表示的块基。
英文摘要:
We give examples of two Banach spaces. One Banach space has no spreading model which contains $\ell_p$ ($1\le p<\infty$) or $c_0$. The other space has an unconditional basis for which $\ell_p$ ($1\le p<\infty$) and $c_0$ are block finitely represented in all block bases.
