关于弱极大化性质

On the Weak Maximizing Properties

Luis C. Garcia-Lirola, Colin Petitjean

摘要:

最近,一个新的性质有关的范数达到运营商已被引入:弱极大化性质(WMP)。在这篇笔记中,我们定义了一个广义版本,它考虑到其他的拓扑比弱的(主要是弱$^*$拓扑)。我们提供了新的充分条件,基于模的渐近一致光滑性和凸性,这意味着一对$(X,Y)$享有一定的极大化性质。这种方法不仅使我们能够(重新)获得作为一个直接的结果,对$(\ell_p,\ell_q)$具有WMP,但也提供了许多更自然的例子,对具有给定的最大化属性。

英文摘要:

Quite recently, a new property related to norm-attaining operators has been introduced: the weak maximizing property (WMP). In this note, we define a generalised version of it considering other topologies than the weak one (mainly the weak$^*$ topology). We provide new sufficient conditions, based on the moduli of asymptotic uniform smoothness and convexity, which imply that a pair $(X,Y)$ enjoys a certain maximizing property. This approach not only allows us to (re)obtain as a direct consequence that the pair $(\ell_p,\ell_q)$ has the WMP, but also provides many more natural examples of pairs having a given maximizing property.
