具有紧结构的$c_0$饱和巴拿赫空间

A $c_0$ saturated Banach space with tight structure

Spiros A. Argyros, Giorgos Petsoulas

摘要:

结果表明,HI方法的变体可以产生与经典巴拿赫空间密切相关的对象。因此,我们提出了一个新的$c_0$饱和空间,记作$\mathfrak{X}_0$,它具有相当紧的结构.空间$\mathfrak{X}_0$不嵌入到具有无条件基的空间中,并且它的补子空间具有以下结构。每个都是I型的,即包含$\mathfrak{X}_0$自身的同构,或者同构于$c_0$的子空间(II型)。此外,对于任何解析分解的$\mathfrak{X}_0$到两个子空间,一个是I型,另一个是II型。$\mathfrak{X}_0$的算子与HI空间的算子具有共同的特征。

英文摘要:

It is shown that variants of the HI methods could yield objects closely connected to the classical Banach spaces. Thus we present a new $c_0$ saturated space, denoted as $\mathfrak{X}_0$, with rather tight structure. The space $\mathfrak{X}_0$ is not embedded into a space with an unconditional basis and its complemented subspaces have the following structure. Everyone is either of type I, namely, contains an isomorph of $\mathfrak{X}_0$ itself or else is isomorphic to a subspace of $c_0$ (type II). Furthermore for any analytic decomposition of $\mathfrak{X}_0$ into two subspaces one is of type I and the other is of type II. The operators of $\mathfrak{X}_0$ share common features with those of HI spaces.
