Continuous biframes in Hilbert Spaces
Hafida Massit, Roumaissae Eljazzar, Mohamed Rossafi
In this paper, we present the concept of continuous biframes in a Hilbert space. We examine the essential properties of biframes with an emphasis on the biframe operator. Moreover,…
Sum of frames in Hilbert modules
Abdellatif Lfounoune, Hafida Massit, Abdelilah Karara +1
In this article, we study g-frames in Hilbert -modules and investigate conditions under which the sum of two g-frames (or a g-frame and a g-Bessel sequence) remains a g-frame.…
Controlled finite continuous frames
Hafida Massit, Mohamed Rossafi, Choonkil Park
In this paper, we present controlled finite continuous frames in a finite dimensional Hilbert space and we study some properties of them. Parseval controlled integral frames are pr…
Pairs of Woven continuous frames in Hilbert spaces
Hafida Massit, Mohamed Rossafi, Samir Kabbaj
In this present paper we introduce weaving Hilbert space frames in the continuous case, we give new approaches for manufacturing pairs of woven continuous frames and we obtain new…
