本文主要研究[Formula:see text]-g-框架的对偶[Formula:see text]-g-Bessel序列。首先利用g-Bessel序列的g-预框架算子研究了[公式:见正文]-g-框架的构造。然后,在考虑g-预框架算子的情况下,给出了g-Bessel序列是给定g-框架的对偶g-Bessel序列的几个充要条件.我们还给出了一个简单的例子来证明[Formula:see text]-g-frames的对偶是不传递的。
This paper is devoted to the study of the dual [Formula: see text]-g-Bessel sequences of [Formula: see text]-g-frames. We firstly make use of the g-preframe operators of a g-Bessel sequence to investigate the constructions of [Formula: see text]-g-frames. And then, taking the g-preframe operators into account, we present several necessary and sufficient conditions under which a g-Bessel sequence is the dual [Formula: see text]-g-Bessel sequence of a given [Formula: see text]-g-frame. We also give a simple example to show that the duality of [Formula: see text]-g-frames is not transitive.
