报告题目:Banach空间的球覆盖性质(Ball-Covering Property of Banach Spaces )
报告摘要:若Banach空间X中的一族不含原点的开球(闭球)B覆盖了整个单位球面,我们就称B为Banach空间X的球覆盖;若X具有可数的球覆盖,我们就称X具有球覆盖性质。我们在报告中会介绍有关Banach空间球覆盖性质的一些结果。By a ball-coveringB of a Banach space X, we mean that B isa collection of open (or closed) balls off the origin whose unioncontains the unit sphere of X; and X is said to have the ball-covering property provided it admits a ball-covering ofcountably many balls. This talk will show some results on ball-covering property of Banach Spaces.
