外$L^{p,\infty}$空间的对偶
Duality for outer $L^{p,\infty}$ spaces
摘要:
测度空间上函数的$L^{p,\infty}$拟范数可以用它们与正规化特征函数的配对来刻画。我们推广这个结果的情况下,外部$L^{p,\infty}$准范数适当的大小。这种刻画为Di Plinio和Fragkos的一篇文章中出现的某些隐式定义的准范数提供了一种明确的形式。
英文摘要:
The $L^{p,\infty}$ quasi-norm of functions on a measure space can be characterized in terms of their pairing with normalized characteristic functions. We generalize this result to the case of the outer $L^{p,\infty}$ quasi-norms for appropriate sizes. This characterization provides an explicit form for certain implicitly defined quasi-norms appearing in an article of Di Plinio and Fragkos.
