摘要
假设 E 和 F 都是巴拿赫网格。众所周知,Fremlin 张量积 \(E{\overline{/otimes }} F\) 上有几个规范可以把它变成一个规范化的网格;特别是投影规范 \(|\pi|\)(称为 Fremlin 投影规范)和注入规范 \(|\epsilon|\)(称为 Wittstock 注入规范)。现在,假设 E 和 F 是局部凸固向量网格。虽然我们已经为张量积 E 和 F 找到了合适的向量网格结构(称为弗雷姆林张量积,用 \(E{\overline\{otimes }}F\ 表示),但一般来说,\(E{\overline\{otimes }}F\ 上缺乏拓扑结构。在本注释中,我们考虑在 \(E{\overline{\otimes }}F\) 上建立线性拓扑结构,使其也成为局部凸固向量网格;这种方法可以作为巴拿赫网格之间弗雷姆林张量乘的投影规范的一般化。
A topology on the Fremlin tensor product of locally convex-solid vector lattices
Suppose that E and F are Banach lattices. It is known that there are several norms on the Fremlin tensor product \(E{\overline{\otimes }} F\) that turn it into a normed lattice; in particular, the projective norm \(|\pi |\) (known as the Fremlin projective norm) and the injective norm \(|\epsilon |\) (known as the Wittstock injective norm). Now, assume that E and F are locally convex-solid vector lattices. Although we have a suitable vector lattice structure for the tensor product E and F (known as the Fremlin tensor product and denoted by \(E{\overline{\otimes }}F\)), there is a lack of topological structure on \(E{\overline{\otimes }}F\), in general. In this note, we consider a linear topology on \(E{\overline{\otimes }}F\) that makes it into a locally convex-solid vector lattice, as well; this approach can be taken as a generalization of the projective norm of the Fremlin tensor product between Banach lattices.
