可逆标架乘子诱导的对偶标架

On the dual frame induced by an invertible frame multiplier

Diana T. Stoeva, Peter Balazs

摘要:

最近,它已经建立,给定一个可逆的帧乘数与半正规化的符号,一个特定的对偶的任何两个涉及的帧可以被确定为反转的目的。逆可以表示为具有倒数符号的乘数,该特定对偶是给定帧之一,而任何对偶是另一帧。特殊对偶是所有贝塞尔序列中唯一具有这种性质的。本文推广了具有上述性质的对偶序列在所有可能序列中是唯一的结果。此外,我们允许符号不一定是半正规化的。最后,我们刻画了典型对偶框架与新的特定对偶框架重合的情形。

英文摘要:

Recently it has been established that given an invertible frame multiplier with semi-normalized symbol, a specific dual of any of the two involved frames can be determined for the inversion purpose. The inverse can be represented as a multiplier with the reciprocal symbol, this particular dual of one of the given frames, and any dual of the other frame. The specific dual is the only one having this property among all Bessel sequences. In this manuscript we extend the results showing that the specific dual with the above mentioned property is unique among all possible sequences. Furthermore, we allow the symbol to be not necessarily semi-normalized. Finally we characterize cases when the canonical dual frame and the new specific dual frame coincide.
