摘要
2016 年,Aldroubi 等人构建了第一类框架,其形式为底层希尔伯特空间上有界线性算子的{Tkφ}k=0∞。在本文中,我们证明了这些框架的一个子类具有一些额外的显著特征,而这些特征在文献中还没有为任何其他框架所发现。最重要的是,无论选择 N∈N,从框架中选择第 N 个元素得到的子族本身就是一个框架。此外,在移除任意有限数量的元素后,框架属性仍然保持不变。
In 2016 Aldroubi et al. constructed the first class of frames having the form for a bounded linear operator on the underlying Hilbert space. In this paper we show that a subclass of these frames has a number of additional remarkable features that have not been identified for any other frames in the literature. Most importantly, the subfamily obtained by selecting each Nth element from the frame is itself a frame, regardless of the choice of . Furthermore, the frame property is kept upon removal of an arbitrarily finite number of elements.
期刊介绍:
Applied and Computational Harmonic Analysis (ACHA) is an interdisciplinary journal that publishes high-quality papers in all areas of mathematical sciences related to the applied and computational aspects of harmonic analysis, with special emphasis on innovative theoretical development, methods, and algorithms, for information processing, manipulation, understanding, and so forth. The objectives of the journal are to chronicle the important publications in the rapidly growing field of data representation and analysis, to stimulate research in relevant interdisciplinary areas, and to provide a common link among mathematical, physical, and life scientists, as well as engineers.
