Hilbert模上算子的 *-框架

*-Frames for operators on Hilbert modules

Mohammad Janfada, Bahram Dastourian

摘要:

K-框架是L.加夫鲁塔研究原子系统的希尔伯特空间。最近,这一概念的一些推广被引入,并研究了它与普通框架的一些区别。本文引入了 *-K-框架,并研究了这类推广的K-框架的一些性质。在证明了 *-K-框架的一些特征之后,讨论了 *-K-框架的直和与张量积,并建立了一些扰动结果.

英文摘要:

K-frames were introduced by L. Gavruta to study atomic systems on Hilbert spaces. Recently some generalizations of this concept are introduced and some of its difference with ordinary frames are studied. In this paper *-K-frames are introduced and some properties of this generalization of K-frames are studied. After proving some characterizations of *-K-frames, direct sum and tensor product of *-K-frames are considered and finally some perturbation results are established.
