弱 * 同胚的自动范数连续性

Automatic norm continuity of weak* homeomorphisms

Antonio Avilés

摘要:

证明了在某类不可分巴拿赫空间E中,对偶球的范数拓扑可用其弱 * 拓扑定义.因此,E中空间的两个球之间的任何弱 * 同胚自动是范数连续的。

英文摘要:

We prove that in a certain class E of nonseparable Banach spaces the norm topology of the dual ball is definable in terms of its weak* topology. Thus, any weak* homeomorphism between duals balls of spaces in E is automatically norm-continuous.
