权矩阵定义的超可微检验函数的傅里叶变换刻画

Characterization of ultradifferentiable test functions defined by weight matrices in terms of their Fourier transform

Gerhard Schindl

摘要:

本文证明了由权矩阵定义的Roumieu型和Beurling型非拟解析类中具有紧支集的函数在某些较弱的正则性条件下可以用其傅里叶变换的衰减性质来刻画.为此,我们引入了从原始矩阵构造多指标矩阵和相关的函数空间的抽象技术。我们详细研究了这种结构的行为,并表征其稳定性。此外,非拟解析类的特点。

英文摘要:

We prove that functions with compact support in non-quasianalytic classes of Roumieu-type and of Beurling-type defined by a weight matrix with some mild regularity conditions can be characterized by the decay properties of their Fourier transform. For this we introduce the abstract technique of constructing from the original matrix multi-index matrices and associated function spaces. We study the behaviour of this construction in detail and characterize its stability. Moreover non-quasianalyticity of the classes is characterized.
