波空间、乘子空间及其在非光滑位势Schr dinger型算子中的应用

Wavelets, Multiplier spaces and application to Schrödinger type operators with non-smooth potentials

Pengtao Li, Qixiang Yang, Yueping Zhu

摘要:

本文利用Meyer小波刻画了索伯列夫空间之间的乘子空间,而不用容量.进一步引入对数Morrey空间$M^{t,τ}_{r,p}(\mathbb{R}^{n})$,建立了Morrey空间与乘子空间之间的包含关系.利用小波特征和分形技巧,构造了一个反例,证明了$M^{t,τ}_{r,p}(\mathbb{R}^{n})$的指标$τ$的范围是尖锐的。作为应用,我们考虑了$M^{t,τ}_{r,p}(\mathbb{R}^{n})$中的一个带位势的薛定谔型算子.

英文摘要:

In this paper, we employ Meyer wavelets to characterize multiplier spaces between Sobolev spaces without using capacity. Further, we introduce logarithmic Morrey spaces $M^{t,τ}_{r,p}(\mathbb{R}^{n})$ to establish the inclusion relation between Morrey spaces and multiplier spaces. By wavelet characterization and fractal skills, we construct a counterexample to show that the scope of the index $τ$ of $M^{t,τ}_{r,p}(\mathbb{R}^{n})$ is sharp. As an application, we consider a Schrödinger type operator with potentials in $M^{t,τ}_{r,p}(\mathbb{R}^{n})$.
