$\mathbb{R}^2$中锥上的Triebel-Lizorkin空间和Shearlet

Triebel-Lizorkin Spaces and Shearlets on the Cone in $\mathbb{R}^2$

Daniel Vera

摘要:

剪切波是具有复合伸缩的小波的一种特殊情况,它具有类似基的结构和多分辨率分析特性。这些相对较新的表示系统已经遇到了广泛的应用,由于其方向敏感性,通常超过其祖先的性能。然而,很少有人知道他们与空间以外的$L^2$。在这里,我们发现了一种各向异性的非齐次Triebel-Lizorkin空间(定义)的所谓的“锥上的剪切波”系数的特征。我们首先证明的分析和综合运营商的有界性与“传统”的剪切系数。然后,随着发展的顺利Parseval框架的剪切波的郭和Labate,我们能够证明再生的身份,这是以前可能的情况下,只有$L^2$。我们还发现一些嵌入的(经典)并矢空间到这些高度各向异性的空间,反之亦然,在一定范围内的参数。为了保持一个简洁的文件,我们开发我们的结果在“失重”的情况下($w=1$),并给出如何开发加权的情况下的提示。

英文摘要:

The shearlets are a special case of the wavelets with composite dilation that, among other things, have a basis-like structure and multi resolution analysis properties. These relatively new representation systems have encountered wide range of applications, generally surpassing the performance of their ancestors due to their directional sensitivity. However, little is known about their relation with spaces other than $L^2$. Here, we find a characterization of a kind of anisotropic inhomogeneous Triebel-Lizorkin spaces (to be defined) with the so called "shearlets on the cone" coefficients. We first prove the boundedness of the analysis and synthesis operators with the "traditional" shearlets coefficients. Then, with the development of the smooth Parseval frames of shearlets of Guo and Labate we are able to prove a reproducing identity, which was previously possible only for the $L^2$ case. We also find some embeddings of the (classical) dyadic spaces into these highly anisotropic spaces, and viceversa, for certain ranges of parameters. In order to keep a concise document we develop our results in the "weightless" case ($w=1$) and give hints on how to develop the weighted case.
