希尔伯特空间中连续框架的乘子

Multipliers for Continuous Frames in Hilbert Spaces

Peter Balazs, Dominik Bayer, Asghar Rahimi

摘要:

本文研究了希尔伯特空间中连续标架乘子的一般理论。这些算子是广泛使用的(离散)帧乘子概念的推广。著名的例子包括Anti-Wick算子、STFT乘子或Calderon-Toeplitz算子。由于潜在的测度空间的可能的特殊性,连续框架的行为不如它们的离散对应物。尽管如此,许多结果类似于离散的情况下证明连续帧乘子,以及,例如紧性和Schatten类性质。此外,控制和加权框架的概念被转移到连续设置。

英文摘要:

In this paper we examine the general theory of continuous frame multipliers in Hilbert space. These operators are a generalization of the widely used notion of (discrete) frame multipliers. Well-known examples include Anti-Wick operators, STFT multipliers or Calderón- Toeplitz operators. Due to the possible peculiarities of the underlying measure spaces, continuous frames do not behave quite as well as their discrete counterparts. Nonetheless, many results similar to the discrete case are proven for continuous frame multipliers as well, for instance compactness and Schatten class properties. Furthermore, the concepts of controlled and weighted frames are transferred to the continuous setting.
