Abstract

We show that the calculation of the sum of local Morrey spaces can be reduced to the calculation of the sum of sequence spaces that appear as parameters in the definition of local Morrey spaces. The presence of such a reduction allows us to obtain new extrapolation theorems for local Morrey spaces with sharp constants.

局部Morrey空间的尖锐外推定理

摘要

我们表明，可以将局部Morrey空间之和的计算简化为对在局部Morrey空间的定义中作为参数出现的序列空间之和的计算。这种减少的存在使我们可以获得具有尖锐常数的局部Morrey空间的新外推定理。
