本文刻画了附属于半有限无原子von Neumann代数且具有Daugavet性质的对称算子空间,其为$L_1(\u039c,\u03c4)$或$\u039c$,相关结果扩展了已有实对称函数空间的Daugavet性质研究。
AI 中文摘要
在温和假设下,本文的主要结果刻画了附属于半有限无原子von Neumann代数$(\u039c, \u03c4)$且具有Daugavet性质的(实或复)对称算子空间,即其为$L_1(\u039c,\u03c4)$或$\u039c$(在等价范数甚至比例范数下)。本文结果对复对称函数空间也是新的,扩展了\uc17b{AKM12, KMMW13, AKM15}中关于实对称函数空间Daugavet性质的结果。
英文摘要
Under mild assumptions, the main results of this paper characterize a (real or complex) symmetric operator space affiliated with a semi-finite atomless von Neumann algebra $(\mathcal M, τ)$ possessing the Daugavet property as $L_1(\mathcal M,τ)$ or $\mathcal M$ (up to equivalent norms, or even proportional norms). Our results are new even for complex symmetric function spaces, which extend results of \cite{AKM12, KMMW13, AKM15} concerning the Daugavet property for real symmetric function spaces.
