加权调制空间中的乘法与复合

Multiplication and Composition in Weighted Modulation Spaces

Maximilian Reich, Winfried Sickel

摘要:

研究了两个加权调制空间乘积的存在性。为此,我们讨论两种不同的策略。更简单的一个允许在各种情况下的透明证明。然而,我们的第二种方法允许更仔细地看相关的规范不等式的限制下,在傅立叶图像。这将使我们有机会处理复合算子的有界性。

英文摘要:

We study the existence of the product of two weighted modulation spaces. For this purpose we discuss two different strategies. The more simple one allows transparent proofs in various situations. However, our second method allows a closer look onto associated norm inequalities under restrictions in the Fourier image. This will give us the opportunity to treat the boundedness of composition operators.
