摘要
广义框架是框架的自然概括。计算框架间的距离是框架理论中的一个重要概念。本文给出了连续框架、连续 g 框架、等价关系和连续 g 框架间距离的一些基本定义和结果。此外,我们还介绍了希尔伯特空间的连续 g 帧与\(L^{2}({\mathfrak {A}})\的封闭子空间之间的一些等价关系,并定义了连续 g 帧之间的距离。最后,我们在近连续 g 帧集上定义了一个新度量,并研究了它的一些性质。
Some relations between continuous generalized frames
Generalized frames are natural generalizations of frames. The computation of distances between frames is a crucial concept in frame theory. In this paper we give some basic definitions and results on continuous frames, continuous g-frames, equivalence relations and distances between continuous g-frames. Furthermore, we introduce some equivalency relations between continuous g-frames for a Hilbert space and closed subspaces of \(L^{2}({\mathfrak {A}})\), and we define a distance between continuous g-frames. Finally, we define a new metric on the set of near continuous g-frames and investigate some of its properties.
