巴拿赫格对偶的理想中心

The ideal center of the dual of a Banach lattice

Mehmet Orhon

摘要:

设$E$是一个巴拿赫格.它的理想中心$Z(E)$自然嵌入其对偶的理想中心$Z(E')$中。这种嵌入可以推广到一个压缩代数和$Z(E)"$到$Z(E')$的格同态。我们证明了扩张是到$Z(E')$上的当且仅当$E$有拓扑满中心. (That是,对于每个$x\in E$,$Z(E)x$的闭包是由$x$生成的闭理想。)这个结果可以推广到Archimedean Riesz空间的序对偶的理想中心,并以修正的形式推广到Archimedean Riesz空间的序对偶上的正形。

英文摘要:

Let $E$ be a Banach lattice. Its ideal center $Z(E)$ is embedded naturally in the ideal center $Z(E')$ of its dual. The embedding may be extended to a contractive algebra and lattice homomorphism of $Z(E)"$ into $Z(E')$. We show that the extension is onto $Z(E')$ if and only if $E$ has a topologically full center. (That is, for each $x\in E$, the closure of $Z(E)x$ is the closed ideal generated by $x$.) The result can be generalized to the ideal center of the order dual of an Archimedean Riesz space and in a modified form to the orthomorphisms on the order dual of an Archimedean Riesz space.
