Webabout Borel probability measures on a separable Banach space. Lemma 8.1.2. Let Ewith norm kk E be a separable, real Banach space, and use (x;x) 2E E 7!hx;xi2R to denote the duality relation between Eand its dual space E . Then the Borel eld B E coincides with the ˙-algebra generated by the maps x2E7!hx;x i as x runs over E . In particular, if ...

Banach Space - an overview ScienceDirect Topics
WebAbstract. In this note we study the problem how the complexification of a real Banach space can be normed in such a way that it becomes a complex Banach space from the point of view of the theory of cross-norms on tensor products of Banach spaces. In particular we show that the norm of a complex Banach lattice can be interpretated in terms of ... WebMoreover, we construct an equivalent almost square bidual norm on \ell_\infty. \ell_\infty. As a consequence we get that every dual Banach space containing c_0 c_0 has an equivalent almost square dual norm. Finally we characterize separable real almost square spaces in terms of their position in their fourth duals. 展开 WebOct 3, 2024 · Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers..
