某些Banach丛截集空间的性质

Properties of the Space of Sections of Some Banach Bundles

Aldo J. Lazar

摘要:

证明了对于某类Banach丛,具有第二个可数局部紧Hausdorff底空间和可分纤维意味着在无穷远处消失的所有截面的巴拿赫空间是可分的。在相反的方向上,证明了对于具有局部紧Hausdorff底空间的Banach丛,无穷远处消失的所有截面的空间的可分性意味着底空间是第二可数的.如果底空间是紧的,并且丛的所有截面的空间由弱紧子集生成,则底空间是Eberlein紧的。

英文摘要:

One shows for Banach bundles in a certain class that having a second countable locally compact Hausdorff base space and separable fibers implies the separability of the Banach space of the all sections that vanish at infinity. In the reverse direction, it is proved that for a Banach bundle with locally compact Hausdorff base space the separability of the space of all the sections that vanish at infinity implies that the base space is second countable. If the base space is compact and the space of all the sections of the bundle is generated by a weakly compact subset then the base space is an Eberlein compact.
