调制空间上多线性局部化算子的连续性

Continuity properties of multilinear localization operators on modulation spaces

Nenad Teofanov

摘要:

我们引入了基于短时傅里叶变换的多线性局部化算子和多线性Weyl伪微分算子。我们证明了这样的本地化运营商实际上是Weyl pseudodiomatic运营商的符号是由本地化运营商的符号和多线性Wigner变换之间的卷积。对于这样的解释,我们使用Gelfand-Shilov空间的Kenrel定理。此外,我们还研究了多线性局部化算子在调制空间上的连续性。我们的结果推广了一些已知的结果时,限制到线性的情况。

英文摘要:

We introduce multilinear localization operators in terms of the short-time Fourier transform, and multilinear Weyl pseudodifferential operators. We prove that such localization operators are in fact Weyl pseudodifferential operators whose symbols are given by the convolution between the symbol of the localization operator and the multilinear Wigner transform. For such interpretation we use the kenrel theorem for the Gelfand-Shilov space. Furthermore, we study the continuity properties of the multilinear localization operators on modulation spaces. Our results extend some known results when restricted to the linear case.
