--frames in Hilbert module over locally--algebras
Roumaissae Eljazzar, Mohammed Mouniane, Mohamed Rossafi
This paper explores the concept of --frames in locally -algebras, which are shown to be more general than -frames. The authors first introduce the notion of a -ort…
Modular Biframes for Operators
Salah Eddine Oustani, Mohamed Rossafi
One of the most important problems in the studying of frames and its extensions is the invariance of these systems under perturbation. The current paper is concerned with the invar…
Continuous bi-g-frames for operators in Hilbert spaces
Abdelilah Karara, Mohamed Rossafi
In this paper, we will introduce the new concepts of continuous bi-g-frames and continuous K-bi-g-frame for Hilbert spaces. Then, we examine some characterizations properties with…
Continuous K-biframes in Hilbert spaces
Abdelilah Karara, Mohamed Rossafi
In this paper, we will introduce the concept of a continuous K-biframe for Hilbert spaces and we present various examples of continuous K-biframes. Furthermore, we investigate thei…
K-bi-g-frames in Hilbert spaces
Abdelilah Karara, Mohamed Rossafi
In this paper, we will introduce the new concept of K-bi-g-frames for Hilbert spaces. Then, we examine some characterizations with the help of a biframe operator. Finally, we inves…
K-biframes in Hilbert spaces
Abdelilah Karara, Mohamed Rossafi
In this paper, we introduce a new concept of K-biframes for Hilbert spaces. We then examine several characterizations with the assistance of a biframe operator. Moreover, we invest…
